Svelte Basics: First Component

I'm going through the Svelte tutorial since it's very comprehensive and up-to-date.

I'm going on a bit of a tangent before I start this post, but I'm straying away from YouTube videos and Udemy courses when learning new programming languages and frameworks. YouTube videos are too fragmented to get good information from. Courses (and YouTube videos) are usually not up-to-date, rendering parts of them useless. Not to mention that you have to pay for free information that's packaged in a course, which is kind of scummy.

Anyway, I've gotten quite a bit further than just the introduction section of Svelte basics, but I don't want to overload myself (or readers) with information.

My First Svelte Component:

This section was relatively straightforward. There wasn't much new information, but I was hooked because of its simplicity. I personally love the idea of having the script tags be a place to define variables and attributes:

<script> let var = "a variable!" </script>

<p>I'm {var}</p>

The example above shows how dynamic attributes are used. I can basically define any variable (and states, but that'll be for the next post) between the script tags that can be used in HTML.

This may seem mundane to programmers experienced in Svelte, but I think it gives really good insight into the philosophy behind Svelte. It's clear that they wanted to keep the language simple and easy to use, and I appreciate that.

As I mentioned in my introductory post, I have a background in React, which has a reputation for being convoluted. Well, maybe that's just my perception, but how Svelte is written is a breath of fresh air!

I look forward to making more posts about what I learn and my attempts at understanding it.

Until next time!

Start Coding Today: Learn React JS for Beginners

Start Coding Today: Learn React JS for Beginners”—will give you a solid foundation and guide you step by step toward becoming a confident React developer.

React JS, developed by Facebook, is an open-source JavaScript library used to build user interfaces, especially for single-page applications (SPAs). Unlike traditional JavaScript or jQuery, React follows a component-based architecture, making the code easier to manage, scale, and debug. With React, you can break complex UIs into small, reusable pieces called components.

Why Learn React JS?

Before diving into the how-to, let’s understand why learning React JS is a smart choice for beginners:

High Demand: React developers are in high demand in tech companies worldwide.

Easy to Learn: If you know basic HTML, CSS, and JavaScript, you can quickly get started with React.

Reusable Components: Build and reuse UI blocks easily across your project.

Strong Community Support: Tons of tutorials, open-source tools, and documentation are available.

Backed by Facebook: React is regularly updated and widely used in real-world applications (Facebook, Instagram, Netflix, Airbnb).

Prerequisites Before You Start

React is based on JavaScript, so a beginner should have:

Basic knowledge of HTML and CSS

Familiarity with JavaScript fundamentals such as variables, functions, arrays, and objects

Understanding of ES6+ features like let, const, arrow functions, destructuring, and modules

Don’t worry if you’re not perfect at JavaScript yet. You can still start learning React and improve your skills as you go.

Setting Up the React Development Environment

There are a few ways to set up your React project, but the easiest way for beginners is using Create React App, a boilerplate provided by the React team.

Step 1: Install Node.js and npm

Download and install Node.js from https://nodejs.org. npm (Node Package Manager) comes bundled with it.

Step 2: Install Create React App

Open your terminal or command prompt and run:

create-react-app my-first-react-app

This command creates a new folder with all the necessary files and dependencies.

Step 3: Start the Development Server

Navigate to your app folder:

my-first-react-app

Then start the app:

Your first React application will launch in your browser at http://localhost:3000.

Understanding the Basics of React

Now that you have your environment set up, let’s understand key React concepts:

1. Components

React apps are made up of components. Each component is a JavaScript function or class that returns HTML (JSX).

function Welcome() { return <h1>Hello, React Beginner!</h1>; }

2. JSX (JavaScript XML)

JSX lets you write HTML inside JavaScript. It’s not mandatory, but it makes code easier to write and understand.

const element = <h1>Hello, World!</h1>;

3. Props

Props (short for properties) allow you to pass data from one component to another.

function Welcome(props) { return <h1>Hello, {props.name}</h1>; }

4. State

State lets you track and manage data within a component.

import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times.</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }

Building Your First React App

Let’s create a simple React app — a counter.

Open the App.js file.

Replace the existing code with the following:

import React, { useState } from 'react'; function App() { const [count, setCount] = useState(0); return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter App</h1> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click Me</button> </div> ); } export default App;

Save the file, and see your app live on the browser.

Congratulations—you’ve just built your first interactive React app!

Where to Go Next?

After mastering the basics, explore the following:

React Router: For navigation between pages

useEffect Hook: For side effects like API calls

Forms and Input Handling

API Integration using fetch or axios

Styling (CSS Modules, Styled Components, Tailwind CSS)

Context API or Redux for state management

Deploying your app on platforms like Netlify or Vercel

Practice Projects for Beginners

Here are some simple projects to strengthen your skills:

Todo App

Weather App using an API

Digital Clock

Calculator

Random Quote Generator

These will help you apply the concepts you've learned and build your portfolio.

Final Thoughts

This “Start Coding Today: Learn React JS for Beginners” guide is your entry point into the world of modern web development. React is beginner-friendly yet powerful enough to build complex applications. With practice, patience, and curiosity, you'll move from writing your first “Hello, World!” to deploying full-featured web apps.

Remember, the best way to learn is by doing. Start small, build projects, read documentation, and keep experimenting. The world of React is vast and exciting—start coding today, and you’ll be amazed by what you can create!

When Your Tech Stack Becomes Your Make-or-Break Decision

Hey tech fam! Ever had that moment when your app starts wheezing under pressure like an old car climbing a hill? That's exactly what happened to one of our clients recently.

Their patient registration system was literally falling apart during peak hours—appointments timing out, users frantically refreshing, and their MEAN stack crying for mercy.

Plot twist: They switched from MEAN to MERN and suddenly it was like trading a bicycle for a sports car!

But here's the real tea: both stacks are JavaScript powerhouses sharing MongoDB, Express, and Node.js. The real showdown is between Angular and React.

"Choosing a tech stack isn't just a checkbox in your project plan—it can be the deciding factor between smooth scaling and unexpected system failure."

Quick breakdown

MEAN (with Angular): Perfect for enterprise-grade apps with complex requirements and larger teams

MERN (with React): Ideal for UI-focused applications where performance and flexibility matter

Which side are you on? Angular's comprehensive framework or React's flexible library approach?

Check out our full breakdown comparing performance, learning curves, and use cases! We've been in the trenches with both MEAN and MERN.
