But it's good to recognize as an alternative to the helper-function break-down above.ġ Yes, a more spacious layout improves this a lot! const luhn = (ds) => reduce ((a, b) => a + b, 0) and last is cleaner than its alternative. 1 But sum (.) is definitely cleaner than (.). Perhaps a more spacious layout would help. This one, especially where we inline the conditional expression (ternary) of doubleDig inside another ternary, seems pretty ugly. While the original version is dense, it's also not hard to follow. Those helper functions are useful, and I would almost always prefer to work with such, but each is called in only one place in our main function, which makes it easy to inline them if we want, and we could write a stand-alone version of this doing so: const luhn = (ds) => We finish by taking the modulus base 10, and report whether that value is 0. We total the results using the helper sum and find the last digit using the helper last, convert it into a number and add it to that total. Now we map over the results, doubling the even digits and casting out nines as necessary (using the helper function doubleDig), but keeping the odd digits intact. slice off the now-first element, which we will only need later as the check-digit. reverse the array to make it easier to track even and odd positions without fiddling with the array length. This function works on the array of single-digit numbers supplied, but also on a string of digits, so that luhn ('4539677908016808') is equivalent to luhn ().įirst we ensure we are working with an array of numbers, with.

So my problem is, that the algorithm is returning all my arrays as valid, my code is below (arrays provided by codecademy): // All valid credit card numbersĬonst valid1 = Ĭonst valid2 = Ĭonst valid3 = Ĭonst valid4 = Ĭonst valid5 = Ĭonst invalid1 = Ĭonst invalid2 = Ĭonst invalid3 = Ĭonst invalid4 = Ĭonst invalid5 = Ĭonst mystery1 = Ĭonst mystery2 = Ĭonst myster圓 = Ĭonst mystery4 = Ĭonst mystery5 = Ĭonst batch = Īnd my function implementing the algorithm: const validateCred = arr => I don't mean to question Luhn's algorithm but seriously I need some clarification on this.

I am currently going through Codecademy's Full Stack Engineer course, up until now I have been perfectly fine with it, discovering new things, working out problems on my own, but this is a serious roadblock in my progression as I just can't seem to identify the problem with this logic.

it’s a mystery pt 4

“I love this song,” Oliver drunkenly leaned over to yell at a complete stranger. “Pop music gets too much shit. The lyrics might be awful, but... the actual music part is good, and it’s still music. Lyrics aren’t necessary for it to count,” he slurred out, peering down at the other. “What’s your favorite kinda music?”
