Ep. 3 - “hopefully failure does not turn into fracture” - John

Dylan C

oh nvm, it was Jack lol

Timmy

I was half a second from muting Ellie on my own during the tribal. Also JACK LEFT 🎉🎉🎉🎉🎉🎉🎉

John

first vote, check. first blindside, check. feels good knowing i helped spearhead the vote flip from stephen onto jack, but if jack comes back he might be out for blood. luckily enough for us worms, the vote morphed into a 7/1 landslide, so he might come after maynor or stephen or keith before me and my peeps. but only time will tell.

Timmy

ELLIE DRINK WATER CHALLENGE, DO THAT CHALLENGE

Keith John

Last night was a tough vote. Jack made people paranoid. Even though i wanted him to stay. No one in my alliance felt easy with him. Even though i wanted jack around as he was good in chllenge and wanted to work with me. But it is what it is.

Raffy

I finally managed to get into an alliance with Ellie and Timmy. Though it is not the biggest, I feel confident that these two will serve me well, at least in the premerge. It's called the Just Go For It Alliance, courtesy of Timmy. And we almost got caught forming it because of Cormac which is iconic. Speaking of him, I don't really know what to make of him. He's very... weird. Like it's hard talking to him, but I feel the same way about Keith so whatever. Plus, I don't really trust Cormac considering he basically made a day 1 alliance with two people on my tribe and Sierra. I need to keep an attentive eye on him.

Ellie

I am so immensely thankful for the tribe call last night. It was filled with things I needed to hear, of course we joked around with the fact that I can’t turn on a stove but I was also so thankful for the amazing people in the call making sure that I take care of myself which I haven’t been doing lately. Life has been really hard on me and it feels like a never get a break, sometimes I neglect taking care of myself because I feel that I physically and mentally can’t. I function on caffeine and I get 2-5 hours of sleep on a good night. Last night was kind of a wake up call because I learned that I am putting myself in danger by neglecting myself and my needs. It was really hard for me to accept that but I feel like I have bonded with these people BEYOND the game, they feel like my family now. Life sucks and I get really unmotivated sometimes and can’t bring myself to get out of bed or even eat, but I’ve gotten a lot better and I hope to continue getting better and the people in that call have already played a huge part in that by motivating me to care about my wellbeing and take care of myself, I will always be thankful for that.

Raffy

I feel like I am bonding well with people? It's hard to get a read on some of them, but I think it's fine for now. Other than that, John came up to me asking for a game bond that I thought we already have. Either way, that seems to be my way into an alliance with him. Hopefully we can grow our numbers and build a trustworthy yet powerful group. We're suspecting a swap pretty soon so I hope that I've bonded with the right people in order to be successful.

Dylan C

I haven’t been socializing enough lately with anyone, and wasn’t going to today but then today was Yikes so. I did miss the tribe call for the challenge because I was on the phone with my friend. Maybe I could’ve made it but eh. Hopefully that one point isn’t going to make or break us. And if it did, well I’ve also done a lot for this challenge already soooo

Ellie

I’m going to be picking flour out of my eyebrows for days

Raffy

I hope we win the challenge. I'm kind of scared that so many things were left blank, but this has got to be enough

Dylan C

BITCH

several of us on this tribe were just on a call saying we didn't wanna vote anyone out smh

I keep agreeing when people say they can't come up with a name for tribal but I do actually have one in mind. I'd say Justin since he seems to be around somewhat less, but it's still not great. I mean, I'd rather not vote anyone

So I've talked with Raffy and Joseph and they agree w/Justin. Haven't specifically mentioned names with anyone else. Ellie says she's just going to listen, and not throw out any names. Also didn't ask my thoughts lol. I'll expand on this more when I record my next video confessional

Timmy

Ughhh we lost, I say we but like I did nothing for the challenge so I was a big contributor to the loss. But now people want justin out and like Justin wants to work with me so I’m not here for that. Honestly I have an alliance that will half the tribe after tomorrow so i would like to have a majority group with him, but I’m still in a good spot without him here. I would rather get Joseph or Dylan R out this round though.

John

okay so apparently cormac wants sierra out after stephen now which is news to me. i just agreed and nodded and was like “okay cool” bc i don’t want to draw negative attention towards myself by acting like i’m trying to protect them, but like i don’t think blindsiding them would be the best move? this game is going to get crazy quick. plus if he’s thinking of taking them out, what if all of a sudden they wanna flip on me? in engineering terms, cracks are propagating on the surface of the material, and it’s not long until failure occurs. hopefully failure does not turn into fracture.

Timmy

Joseph and I haven’t spoken in a few days yet he messages just saying “so, tribal” in bold and I’m like wtf like I’m not gonna talk to you about tribal yet, I need to see if I can trust you first.

Dylan C

What is the big risk I'm taking for the idol and risking my vote at tribal? A fucking puzzle with a shit ton of blue sky and snow, and the piece are weird and r o t a t e. I'm not getting this shit done by 11pm tomorrow! Not when I'm in classes all day, and then have DnD not long after. And I made an account to save my progress, putting my name in it so if I do finish and end up on the leaderboard for someone else to see. You know what I've got tonight? BDE. That's right: big dummy energy. At least the vote seems almost unanimous at this point, so that could easily change, but if it goes like it seems like it will then my vote won't matter too much.

Dylan C

41 minutes and 40 second in, 32%, brain is fried JustinAlright so I am a bit nervous for this tribal considering I have not been too active for this round, but I am still confident I can move the target onto someone else. I was thinking I can possibly get people to vote out Dylan R considering he has been more inactive than I have. Although, the other tribe blindsiding Jack makes me weary because it might have caused people on my tribe to make a move against a more active player. So, I need to be on my toes to make sure that is not me. Also, remember how I said I want to work with Timmy? Well I messaged that bitch asking if he wants to work with me officially, but he hasn't answered even though he has been online since I have sent the message. So, honestly I might try to target him considering he has not been super active either.

Keith John

I have been a bit busy these past few days, havnt spoken to everyone much. Good thing we won immunity. So scrambling is at its minimum. i got a feeling a swap is coming up. Makes me nervous. I dont have many connections on the other side.

Except Justin, spoke to him a few times. Raffy and Ellie I spoke to but they feel like people who talk to everyone. so I dont know if they have my back. Whilst Timmy even didnt reply to my hi. As guess he is clear about not working with me

Stephen

Hi. My name is Mr Immune, which I almost misspelt as Mt Immune, wouldn’t that be entertaining? Anyway the tribes feeling good, John and Sierra are cool, Zoes nice, Maynors nice but oddly distant. Everythings middle of the road atm, nothing great but nothing sucky. I’ll probably try and cruise for a bit on social connections until swap or something equally spicy pops up.

Maynor

I have continued doing the puzzles and I have 3 of them left. Hopefully the idol isnt found yet. We’ll see. Im so happy we were able to win immunity cuz i was slowly freaking out that Jack said my name. Atleast i just screamed inside my head and didnt become as paranois as Jack. He literally made himself the target. Everyone agreed on Stephen then his paranoia happened and it switched onto him.

P.S. ❤️ Jay

Sierra

After Jack got voted out, I was worried that we were going to lose the next challenge. I was so relieved when we actually pulled through and won! We all really worked so hard to win that one... and even though I’m in an alliance, I’d rather not have to test things again just yet.

Raffy

God I hate tribal. It’s ugly. Though I instantly have a name in mind: Justin. He’s the person I trust the least and have talked to the least. I talked to Ellie and Dylan C about it. They seemed to be on board with the whole thing. We just need one more vote which should be easy to get. After all, I am in an alliance with Timmy, so it should be easy for me to get four votes. I’m just hoping that he doesn’t have an idol.

Last night, I was talking to Dylan a little bit. Apparently, they are are scared that they haven’t been added to any alliances and they feel like alliances are being made. So I suggested making an alliance with them and I. They’re in a vulnerable position which is great for me since it means they’ll be more willing to work with me. After tribal, I’m hoping that we can create an alliance together with some other people. I’m excited!!!

Ellie

So it’s between Justin and Dylan R and I have the deciding vote?? More drama coming soon

Justin

Ok these bitches are making me mad. I approached Ellie and Dylan C for alliances. Luckily, they both said yes to individual alliances, but as soon as I brought up the idea for all of us to join together plus Raffy they go mute. That is definitely concerning, but I brought up Dylan R’s name to all three as a target this vote and I can only hope they stick to their word to vote them out. I also made an official alliance with Keith, and he spilled the beans that he has been talking to Raffy a bit which makes me nervous. However, I have changed my stance on Raffy because he actually talks to me quite a lot. But, I am aware he is definitely playing this game hard and is talking to almost everyone. That is why I want to keep him close for the time being and then perhaps blindside him in a swap or early merge. Back to Keith tho, he is ITCHING to make a move. He told me it is his first time playing an ORG and he definitely wants to blindside people which as long as it ain’t me I’m good.

Joseph Collins

Me and Elle have been working so good together. I hope she doesn’t stab me in the back lol. The tribe consensus was Justin but I flipped them all to Dylan r. Blindsideeeeee coming. Hahahahaha. *evil laugh* *winky face

Joseph Collins

Lemme break down how I flipped the vote. I just told Dylan c that “look. I respect you. And I’d want someone to do this for me. The tide’s changing and I think the vote is gonna be Dylan R tonight. I don’t want you to be left out of a vote because I wanted to work with you so I feel like you should know” that establishes trust and kinda gets Dylan to switch her vote

John

i’m ready to make a legitimate move in this game. but it’s all about timing. our best move, if we lose again, is sending stephen outta here. WITH THAT BEING SAID, it’s on after that. bring on the bloodbath. not everything will be happy go lucky for long.

Joseph Collins

I orchestrated this blindside and took no credit in my voting message. Like a true mastermind. *maniacal laugh*

Justin

Biiiiiiiitch. I just found out bitches have been conspiring against me cuz of the time zone difference. So, I was right for being paranoid omg. The person who initially told me was Joseph of all people which was shocking since I probably talk to him the least besides Dylan R. But, I’m glad he did and then Timmy further confirmed it which I’m like hello again Timmy it’s been a bit bud. From what they have told me is that the majority is still on Dylan R. and I talked to Dylan C. about the vote and I straight up talked about the time zone difference not being an issue. They said they have a friend in Scotland so it doesn’t bother them so if at least those three and myself vote Dylan R. then I should be good.

Raffy

The tribe has switched their mentality and have decided to go with Dylan R. with this vote which I am fine with considering he does not talk to me at all either. Plus, Justin came up to me asking if we could align together in this game which is always a good sign. So, I was more inclined to keep him throughout the day. Either way, I think I should be safe at this tribal council.

Zoe

I’m a wild bitch.

For the scavenger hunt challenge, I definitely got a tattoo (of the water tribe symbol from avatar, don’t @ me) for a whopping 20 points, and we definitely won the challenge. While riding on that high I accidentally talked about the idol hunt and got a strike from the god-host, which made me feel like the ultimate failure. Other than that, I have several strong alliances which I am confident in going into the swap.

Dylan C

https://youtu.be/gpUevTrixLo

https://youtu.be/_Qpn_dE6fxs

Not feeling like typing this up in detail but the vote has now changed to Dylan R and I’m down with/that. I talked to some people about it and they agree. Joseph messaged me and was like “I feel I have to tell you since you said you wanted to vote Justin.” I was like “that’s sweet but I already knew.” And kinda tried to play it off after that like I’m a little worse at socializing than I actually am but idk how well that worked. I really should’ve made this confession 5 hours ago but oh well. (Those videos were filmed almost 12 hours ago).

Dylan C

I actually finished the fucking puzzle and I can’t believe it. Also if I hadn’t, it would’ve counted against me next tribal, not tonight’s. Either way, I’m not losing that vote via that puzzle babey.

I Don’t Hate Arrow Functions

TL;DR

Arrow functions are fine for certain usages, but they have so many variations that they need to be carefully controlled to not break down the readability of the code.

While arrow functions clearly have a ubiquitous community consensus (though not unanimous support!), it turns out there’s a wide variety of opinions on what makes “good” usage of => and not.

Configurable linter rules are the best solution to wrangling the variety and disagreement of arrow functions.

I released proper-arrows ESLint plugin with several configurable rules to control => arrow functions in your code base.

Opinions are like noses…

Anyone who’s followed me (tweets, books, courses, etc) for very long knows that I have lots of opinions. In fact, that’s the only thing I’m an expert on — my own opinions — and I’m never at a loss for them!

I don’t subscribe to the “strong opinions, loosely held” mantra. I don’t “loosely hold” my opinions because I don’t see any point in having an opinion if there isn’t sufficient reason for that opinion. I spend a lot of time researching and tinkering and writing and trying out ideas before I form an opinion that I would share publicly. By that point, my opinion is pretty strongly held, by necessity.

What’s more, I teach based on these opinions — thousands of developers in different companies all over the world — which affords me the opportunity to deeply vet my opinions through myriad discussion and debate. I’m tremendously privleged to be in such a position.

That doesn’t mean I can’t or won’t change my opinions. As a matter of fact, one of my most strongly held opinions — that JS types and coercion are useful in JS — has been shifting lately, to a fairly significant degree. I have a much more rounded and deepened perspective on JS types and why type-aware tooling can be useful. And even my opinion on => arrow functions, the punchline of this article, has evolved and deepened.

But one of the things many people tell me they appreciate about me is, I don’t just state opinions, I back those opinions up with careful, thought-out reasoning. Even when people vehemently disagree with my opinions, they often compliment me on at least owning those opinions with backing.

And I try to inspire the same in others through my speaking, teaching, and writing. I don’t care if you agree with me, I only care that you know why you have an technical opinion and can earnestly defend it with your own line of reasoning. To me, that’s a healthy relationship with technology.

Arrow Functions != functions

It is my sincere belief that the => arrow function is not suitable as a general purpose replacement for all (or even most) function functions in your JS code. I genuinely don’t find them more readable in most cases. And I’m not alone. Any time I share an opinion like that on social media, I often get dozens of “me too!” responses peppered in with the scores of “you’re totally wrong!” responses.

But I’m not here to rehash the entire debate over => arrow functions. I’ve written extensively about my opinions on them, including these sections in my books:

“You Don’t Know JS: ES6 & Beyond”, Ch2, “Arrow Functions”

“Functional-Light JavaScript”, Ch2, “Functions Without function“ (and the preceding section on function names).

Whatever your preferences around =>, to suggest that it’s only a better function is to be plainly reductive. It’s a far more nuanced topic than just a one-to-one correspondence.

There are things to like about =>. You might find that surprising for me to say, since most people seem to assume I hate arrow functions.

I don’t (hate them). I think there are definitely some important benefits.

It’s just that I don’t unreservedly endorse them as the new function. And these days, most people aren’t interested in nuanced opinions in the middle. So since I’m not entirely in the pro-=> camp, I must be entirely in the opposition camp. Not true.

What I hate is suggesting they’re universally more readable, or that they’re objectively better in basically all cases.

The reason I reject this stance is because I REALLY DO STRUGGLE TO READ THEM in many cases. So that perspective just makes me feel dumb/inferior as a developer. “There must be something wrong with me, since I don’t think it’s more readable. Why do I suck so much at this?” And I’m not the only one whose impostor syndrome is seriously stoked by such absolutes.

And the cherry on top is when people tell you that the only reason you don’t understand or like => is because you haven’t learned them or used them enough. Oh, right, thanks for the (condescending) reminder it’s due to my ignorance and inexperience. SMH. I’ve written and read literally thousands of =>functions. I’m quite certain I know enough about them to hold the opinions I have.

I’m not in the pro-=> camp, but I recognize that some really do prefer them, legitimately. I recognize that some people come to JS from languages that have used => and so they feel and read quite natural. I recognize that some prefer their resemblance to mathematical notation.

What’s problematic IMO is when some in those camps simply cannot understand or empathize with dissenting opinions, as if there must just be something wrong with them.

Readability != Writability

I also don’t think you know what you’re talking about when you talk about code readability. By and large, the vast majority of opinions on code readability, when you break them down, are based on a personal stance about preferences in writingconcise code.

When I push back in debates about code readability, some just dig in their heels and refuse to support their opinion. Others will waive off the concerns with, “readability is all just subjective anyway”.

The flimsiness of that response is stunning: two seconds ago they were vehemently claiming => arrow is absolutely and objectively more readable, and then when pressed, they admit, “well, I think it’s more readable, even if ignorants like you don’t.”

Guess what? Readability is subjective, but not entirely so. It’s a really complex topic. And there are some who are undertaking to formally study the topic of code readability, to try to find what parts of it are objective and what parts are subjective.

I have read a fair amount of such research, and I’m convinced that it’s a complicated enough topic that it can’t be reduced to a slogan on a t-shirt. If you want to read them, I would encourage you doing some google searching and reading of your own.

While I don’t have all the answers myself, one thing I’m certain about is, code is more often read than written, so perspectives on the topic which ultimately come from “it’s easier/quicker to write” don’t hold much standing. What needs to be considered is, not how much time do you save writing, but how clearly will the reader (future you or someone else on the team) be able to understand? And ideally, can they mostly understand it without pouring over the code with a fine-toothed comb?

Any attempt to justify writability affordances with unsubstantiated claims about readability benefits is a weak argument at best, and in general, nothing but a distraction.

So I roundly reject that => is always and objectively “more readable”.

But I still don’t hate arrow functions. I just think to use them effectively, we need to be more disciplined.

Linters == Discipline

You might be of the (incorrect) belief that linters tell you objective facts about your code. They can do that, but that’s not their primary purpose.

The tool that’s best suited to tell you if your code is valid is a compiler (ie, the JS engine). The tool that’s best suited to tell you whether your code is “correct” (does what you want it to do) is your test suite.

But the tool that’s best suited to tell you if your code is appropriate is a linter. Linters are opinionated collections of rules about how you should style and structure your code, so as to avoid likely problems — according to the authors of those opinion-based rules.

That’s what they’re for: to apply opinions to your code.

That means it’s almost certain that these opinions will, at one time or another, “offend” you. If you’re like most of us, you fancy yourself pretty good at what you do, and you know that this thing you’re doing on this line of code is right. And then the linter pops up and says, “Nope, don’t do it that way.”

If your first instinct is sometimes to disagree, then you’re like the rest of us! We get emotionally attached to our own perspectives and abilities, and when a tool tells us we’re wrong, we chuff a little bit.

I don’t get mad at the test suite or the JS engine. Those things are all reporting facts about my code. But I can definitely get irritated when the linter’s opinion disagrees with mine.

I have this one linter rule that I enabled a few weeks ago, because I had an inconsistency in my coding that was annoying me on code re-reads. But now this lint rule is popping up two or three times an hour, nagging me like a stereotypical grandma on a 90’s sitcom. Every single time, I ponder (for just a moment) if I should just go disable that rule. I leave it on, but to my chagrin.

So why subject ourselves to this torment!? Because linter tools and their opinions are what give us discipline. They help us collaborate with others.

They ultimately help us communicate more clearly in code.

Why shouldn’t we let every developer make their own decisions? Because of our tendency toward emotional attachment. While we’re in the trenches working on our own code, against unreasonable pressure and deadlines, we’re in the least trustable mindset to be making those judgement calls.

We should be submitting to tools to help us maintain our discipline.

It’s similar to how TDD advocates submit to the discipline of writing tests first, in a formal set of steps. The discipline and the bigger picture outcome of the process are what we value most, when we’re level headed enough to make that analysis. We don’t institute that kind of process when our code is hopelessly broken and we have no idea why and we’re just resorting to trying random code changes to see if they fix it!

No. If we’re being reasonable, we admit that the overall good is best served when we set up reasonable guidelines and then follow the discipline of adhering to them.

Configurability Is King

If you’re going to knowingly subject yourself to this finger wagging, you (and your team, if applicable) are certainly going to want some say-so in what rules you’re required to play by. Arbitrary and unassailable opinions are the worst kind.

Remember the JSLint days when 98% of the rules were just Crockford’s opinions, and you either used the tool or you didn’t? He straight up warned you in the README that you were going to be offended, and that you should just get over it. That was fun, right? (Some of you may still be using JSLint, but I think you should consider moving on to a more modern tool!)

That’s why ESLint is king of the linters these days. The philosophy is, basically, let everything be configurable. Let developers and teams democratically decide which opinions they all want to submit to, for their own discipline and good.

That doesn’t mean every developer picks their own rules. The purpose of rules is to conform code to a reasonable compromise, a “centralized standard”, that has the best chance of communicating most clearly to the most developers on the team.

But no rule is ever 100% perfect. There’s always exception cases. Which is why having the option to disable or re-configure a rule with an inline comment, for example, is not just a tiny detail but a critical feature.

You don’t want a developer to just have their own local ESLint config that overrides rules while they commit code. What you want is for a developer to either follow the established rules (preferred!) OR to make an exception to the rules that is clear and obvious right at the point where the exception is being made.

Ideally, during a code review, that exception can be discussed and debated and vetted. Maybe it was justified, maybe it wasn’t. But at least it was obvious, and at least it was possible to be discussed in the first place.

Configurability of tools is how we make tools work for us instead of us working for the tools.

Some prefer convention-based approaches to tooling, where the rules are pre-determined so there’s no discussion or debate. I’m know that works for some developers and for some teams, but I don’t think it is a sustainable approach for generalized, broad application. Ultimately, a tool that is inflexible to the changing project needs and DNA of the developer(s) using it, will end up falling into obscurity and eventually replaced.

Proper Arrows

I fully recognize my usage of the the word “proper” here is going to ruffle some feathers. “Who is getify to say what is proper and not?”

Remember, I’m not trying to tell you what is proper. I’m trying to get you to embrace the idea that opinions about => arrow functions are as varied as all the nuances of their syntax and usage, and that ultimately what is most appropriate is that some set of opinions, no matter what they are, should be applicable.

While I’m a big fan of ESLint, I’ve been disappointed by the lack of support from built-in ESLint rules for controlling various aspects of => arrow functions. There are a few built-in rules, but I’m frustrated that they seem to focus mostly on superficial stylistic details like whitespace.

I think there are a number of aspects that can hamper => arrow function readability, issues that go way beyond what the current ESLint ruleset can control. I asked around on twitter, and it seems from the many replies that a lot of people have opinions on this.

The ultimate linter would not only let you configure rules to your liking, but build your own rules if something were lacking. Luckily, ESLint supports exactly that!

So I decided to build an ESLint plugin to define an additional set of rules around => arrow functions: proper-arrows.

Before I explain anything about it, let me just point out: it’s a set of rules that can be turned on or off, and configured, at your discretion. If you find even one detail of one rule helpful, it would be better to use the rule/plugin than not.

I’m fine with you having your own opinions on what makes => arrow functions proper. In fact, that’s the whole point. If we all have different opinions on => arrow functions, we should have tooling support to let us pick and configure those different opinions.

The philosophy of this plugin is that, for each rule, when you turn the rule on, you get all of its reporting modes on by default. But you can of course either not turn the rule on, or turn the rule on and then configure its modes as you see fit. But I don’t want you to have to go hunting for rules/modes to turn on, where their obscurity prevents them from even being considered. So everything comes on per rule.

The only exception here is that by default, all rules ignore trivial => arrow functions, like () => {}, x => x, etc. If you want those to be checked, on a per-rule basis you have to turn on that checking with the { "trivial": true } option.

Proper Arrows Rules

So what rules are provided? Here’s an excerpt from the project overview:

"params": controls definitions of => arrow function parameters, such as forbidding unused parameters, forbidding short/unsemantic parameter names, etc.

"name": requires => arrow functions to only be used in positions where they receive an inferred name (i.e., assigned to a variable or property, etc), to avoid the poor readbility/debuggability of anonymous function expressions.

"location": restricts where in program structure => arrow functions can be used: forbidding them in the top-level/global scope, object properties, export statements, etc.

"return": restricts the concise return value kind for => arrow functions, such as forbidding object literal concise returns (x => ({ x })), forbidding concise returns of conditional/ternary expressions (x => x ? y : z), etc.

"this": requires/disallows => arrow functions using a this reference, in the => arrow function itself or in a nested => arrow function. This rule can optionally forbid this-containing => arrow functions from the global scope.

Remember, each rule has various modes to configure, so none of this is all-or-nothing. Pick what works for you.

As an illustration of what the proper-arrows rules can check for, let’s look at the "return" rule, specifically its "sequence" mode. This mode refers to the concise return expression of => arrow functions being a comma-separated sequence, like this:

var myfunc = (x,y) => ( x = 3, y = foo(x + 1), [x,y] );

Sequences are typically used in => arrow function concise returns to string together multiple (expression) statements, without needing to use a full { .. } delimited function body and an explicit return statement.

Some may love this style — that’s OK! — but a lot of folks think it favors clever terse style coding over readability, and would prefer instead:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

Notice that it’s still an => arrow function and it’s not even that many more characters. But it’s clearer that there are three separate statements in this function body.

Even better:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

To be clear, the proper-arrows rules don’t enforce trivial styling differences like whitespace/indentation. There are other (built-in) rules if you want to enforce those requirements. proper-arrows focuses on what I consider to be more substantive aspects of => function definition.

Concise Summary

You and I almost certainly disagree on what makes good, proper => arrow function style. That’s a good and healthy thing.

My goal here is two-fold:

Convince you that opinions on this stuff vary and that’s OK.

Enable you to make and enforce your own opinions (or team consensus) with configurable tooling.

There’s really nothing to be gained from arguing over opinion-based rules. Take the ones you like, forget the ones you don’t.

I hope you take a look at proper-arrows and see if there’s anything in there which you could use to ensure your => arrow functions are the best form they can be in your code base.

And if the plugin is missing some rules that would help define more proper arrows, please file an issue and we can discuss! It’s entirely plausible we may add that rule/mode, even if I personally plan to keep it turned off!

I don’t hate => arrow functions, and you shouldn’t either. I just hate uninformed and undisciplined debate. Let’s embrace smarter and more configurable tooling and move on to more important topics!

But I’m not here to rehash the entire debate over => arrow functions. I’ve written extensively about my opinions on them, including these sections in my books:

“You Don’t Know JS: ES6 & Beyond”, Ch2, “Arrow Functions”

“Functional-Light JavaScript”, Ch2, “Functions Without function“ (and the preceding section on function names).

Whatever your preferences around =>, to suggest that it’s only a better function is to be plainly reductive. It’s a far more nuanced topic than just a one-to-one correspondence.

There are things to like about =>. You might find that surprising for me to say, since most people seem to assume I hate arrow functions.

I don’t (hate them). I think there are definitely some important benefits.

What I hate is suggesting they’re universally more readable, or that they’re objectively better in basically all cases.

What’s problematic IMO is when some in those camps simply cannot understand or empathize with dissenting opinions, as if there must just be something wrong with them.

Readability != Writability

Any attempt to justify writability affordances with unsubstantiated claims about readability benefits is a weak argument at best, and in general, nothing but a distraction.

So I roundly reject that => is always and objectively “more readable”.

But I still don’t hate arrow functions. I just think to use them effectively, we need to be more disciplined.

Linters == Discipline

You might be of the (incorrect) belief that linters tell you objective facts about your code. They can do that, but that’s not their primary purpose.

That’s what they’re for: to apply opinions to your code.

I don’t get mad at the test suite or the JS engine. Those things are all reporting facts about my code. But I can definitely get irritated when the linter’s opinion disagrees with mine.

So why subject ourselves to this torment!? Because linter tools and their opinions are what give us discipline. They help us collaborate with others.

They ultimately help us communicate more clearly in code.

We should be submitting to tools to help us maintain our discipline.

No. If we’re being reasonable, we admit that the overall good is best served when we set up reasonable guidelines and then follow the discipline of adhering to them.

Configurability Is King

Configurability of tools is how we make tools work for us instead us working for the tools.

Proper Arrows

I fully recognize my usage of the the word “proper” here is going to ruffle some feathers. “Who is getify to say what is proper and not?”

The ultimate linter would not only let you configure rules to your liking, but build your own rules if something were lacking. Luckily, ESLint supports exactly that!

So I decided to build an ESLint plugin to define an additional set of rules around => arrow functions: proper-arrows.

Proper Arrows Rules

So what rules are provided? Here’s an excerpt from the project overview:

"params": controls definitions of => arrow function parameters, such as forbidding unused parameters, forbidding short/unsemantic parameter names, etc.

"location": restricts where in program structure => arrow functions can be used: forbidding them in the top-level/global scope, object properties, export statements, etc.

Remember, each rule has various modes to configure, so none of this is all-or-nothing. Pick what works for you.

var myfunc = (x,y) => ( x = 3, y = foo(x + 1), [x,y] );

Some may love this style — that’s OK! — but a lot of folks think it favors clever terse style coding over readability, and would prefer instead:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

Notice that it’s still an => arrow function and it’s not even that many more characters. But it’s clearer that there are three separate statements in this function body.

Even better:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

Concise Summary

You and I almost certainly disagree on what makes good, proper => arrow function style. That’s a good and healthy thing.

My goal here is two-fold:

Convince you that opinions on this stuff vary and that’s OK.

Enable you to make and enforce your own opinions (or team consensus) with configurable tooling.

There’s really nothing to be gained from arguing over opinion-based rules. Take the ones you like, forget the ones you don’t.

I hope you take a look at proper-arrows and see if there’s anything in there which you could use to ensure your => arrow functions are the best form they can be in your code base.

RAC CAR INSURANCE HELP!?

I purchased car insurance from RAC last year, they then annulled it as said I could not use my no claims bonus on two cars and sent me a new quote. I rang them up and they then said I haven't sent the no claims bonus documents in so I faxed them through once again, I advised I received this letter but they said just send in the documents which I did. I also never received any documents for my cover so had to request these myself which were sent by email for 25.00 :S. After hearing nothing back I rang rac for an update who said my new insurance quote was double the original quote!! I haven't signed any paperwork or received any paperwork advising they automatically gave me new insurance. I asked them to cancel but they said I have to pay 1000 as well as them keeping my deposit and paying for the first months insurance..1000?? I told them no. Paid what i owed for the first month. Now they are sending me letter telling me to pay..do I really have to do this?? I haven't signed anything even for the original insurance as they never sent the paperwork out, and as the insurance was annulled can they really automatically start a new insurance without my permission??

Is health insurance worth getting if you are 23?

I just started working my first real adult job and have become eligible for a health insurance package.

I'm 23 (female) and I never get sick and I haven't had the need to go to the the doctor for anything serious in over 4 years. It may seem like a stupid question since Health Coverage right now is a current hot topic that many people are fighting about, but....SHOULD I GET MY BENEFITS? I just don't see the point of having all that money taken out of my paycheck and then STILL having to pay a co-pay. I might go see a Obgyn but that costs less than $250 out off pocket which is still less than $2112.

I Don’t Hate Arrow Functions

TL;DR

Arrow functions are fine for certain usages, but they have so many variations that they need to be carefully controlled to not break down the readability of the code.

While arrow functions clearly have a ubiquitous community consensus (though not unanimous support!), it turns out there’s a wide variety of opinions on what makes “good” usage of => and not.

Configurable linter rules are the best solution to wrangling the variety and disagreement of arrow functions.

I released proper-arrows ESLint plugin with a variety of configurable rules to control => arrow functions in your code base.

Opinions are like noses…

But one of the things many people tell me they appreciate about it me is, I don’t just state opinions, I back those opinions up with careful, thought-out reasoning. Even when people vehemently disagree with my opinions, they often compliment me on at least owning those opinions with backing.

Arrow Functions != functions

But I’m not here to rehash the entire debate over => arrow functions. I’ve written extensively about my opinions on them, including these sections in my books:

“You Don’t Know JS: ES6 & Beyond”, Ch2, “Arrow Functions”

“Functional-Light JavaScript”, Ch2, “Functions Without function“ (and the preceding section on function names).

Whatever your preferences around =>, to suggest that it’s only a better function is to be plainly reductive. It’s a far more nuanced topic than just a one-to-one correspondence.

There are things to like about =>. You might find that surprising for me to say, since most people seem to assume I hate arrow functions.

I don’t (hate them). I think there are definitely some important benefits.

What I hate is suggesting they’re universally more readable, or that they’re objectively better in basically all cases.

The reason I reject this stance is because I REALLY DO STRUGGLE TO READ THEM in many cases. So that perspective just makes me feel dumb/inferior as a developer. “There must be something wrong with me, since I don’t think it’s more readable. Why do I suck so much at this?” And I’m not the only one who’s impostor syndrome is seriously stoked by such absolutes.

And the cherry on top is when people tell you that the only reason you don’t understand or like => is because you haven’t learned them or used them enough. Oh, right, it’s my ignorance. SMH. I’ve written and read literally thousands of =>functions. I’m quite certain I know enough about them to hold the opinions I have.

What’s problematic IMO is when some in those camps simply cannot understand or empathize with dissenting opinions, as if there must just be something wrong with them.

Readability != Writability

Any attempt to justify writability affordances with unsubstantiated claims about readability benefits is a weak argument at best, and in general, nothing but a distraction.

So I roundly reject that => is always and objectively “more readable”.

But I still don’t hate arrow functions. I just think to use them effectively, we need to be more disciplined.

Linters == Discipline

You might be of the (incorrect) belief that linters tell you objective facts about your code. They can do that, but that’s not their primary purpose.

That’s what they’re for: to apply opinions to your code.

I don’t get mad at the test suite or the JS engine. Those things are all reporting facts about my code. But I can definitely get irritated when the linter’s opinion disagrees with mine.

So why subject ourselves to this torment!? Because linter tools and their opinions are what give us discipline. They help us collaborate with others.

They ultimately help us communicate more clearly in code.

We should be submitting to tools to help us maintain our discipline.

No. If we’re being reasonable, we admit that the overall good is best served when we set up reasonable guidelines and then follow the discipline of adhering to them.

Configurability Is King

Configurability of tools is how we make tools work for us instead us working for the tools.

Proper Arrows

I fully recognize my usage of the the word “proper” here is going to ruffle some feathers. “Who is getify to say what is proper and not?”

The ultimate linter would not only let you configure rules to your liking, but build your own rules if something were lacking. Luckily, ESLint supports exactly that!

So I decided to build an ESLint plugin to define an additional set of rules around => arrow functions: proper-arrows.

Proper Arrows Rules

So what rules are provided? Here’s an excerpt from the project overview:

"params": controls definitions of => arrow function parameters, such as forbidding unused parameters, forbidding short/unsemantic parameter names, etc.

"location": restricts where in program structure => arrow functions can be used: forbidding them in the top-level/global scope, object properties, export statements, etc.

Remember, each rule has various modes to configure, so none of this is all-or-nothing. Pick what works for you.

var myfunc = (x,y) => ( x = 3, y = foo(x + 1), [x,y] );

Some may love this style — that’s OK! — but a lot of folks think it favors clever terse style coding over readability, and would prefer instead:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

Notice that it’s still an => arrow function and it’s not even that many more characters. But it’s clearer that there are three separate statements in this function body.

Even better:

var fn2 = (x,y) => { x = 3; y = foo(x + 1); return [x,y]; };

Concise Summary

You and I almost certainly disagree on what makes good, proper => arrow function style. That’s a good and healthy thing.

My goal here is two-fold:

Convince you that opinions on this stuff vary and that’s OK.

Enable you to make and enforce your own opinions (or team consensus) with configurable tooling.

There’s really nothing to be gained from arguing over opinion-based rules. Take the ones you like, forget the ones you don’t.

I hope you take a look at proper-arrows and see if there’s anything in there which you could use to ensure your => arrow functions are the best form they can be in your code base.

I don’t hate => arrow functions, and you shouldn’t either. I just hate uninformed and unenforced debate. Let’s embrace smarter and more configurable tooling and move on to more important topics!
