Pre-requisites: Installing Node.js, npm, and Your Editor

Before starting with React, Vue, or Angular, you’ll need:

  1. Node.js – JavaScript runtime for running and building projects.

    • Download Node.js

    • Install LTS (Long Term Support) version for stability.

    • Verify installation:

      bash
      node -v
      npm -v

  2. Code Editor – VS Code is the most popular choice.

  3. Basic JavaScript Knowledge – Understand variables, functions, and arrays.

Section 1: Learning React

What is React?

React is a JavaScript library developed by Facebook for building component-based user interfaces. It’s known for its virtual DOM, which updates UI efficiently.

Step 1: Setting Up Your First React App

bash
npx create-react-app my-app
cd my-app
npm start

  • This creates a basic React project with everything you need to start coding.

  • Open src/App.js and modify your first component.

Step 2: Your First React Component

jsx
function App() {
return (
<div>
<h1>Hello React!</h1>
<p>Welcome to your first React app.</p>
</div>
);
}
export default App;

Save, and your browser will refresh instantly.

Step 3: Best Practices for React Beginners

  • Use functional components and hooks (useState, useEffect).

  • Keep components small and reusable.

  • Maintain a clear folder structure (components/, pages/).

  • Use PropTypes or TypeScript for type safety.

Step 4: Common React Mistakes

  • Mutating state directly – Always use the setState function.

  • Not using keys in lists – Helps React identify elements.

  • Too much logic in components – Move logic to hooks or utilities.

Step 5: Learning Resources for React

Section 2: Learning Vue

What is Vue?

Vue.js is a progressive JavaScript framework created by Evan You. It’s simple to start with and powerful enough for large-scale apps.

Step 1: Setting Up Your First Vue App

bash
npm init vue@latest
cd my-vue-app
npm install
npm run dev

Step 2: Your First Vue Component

vue
<template>
<h1>Hello Vue!</h1>
<p>Welcome to your first Vue app.</p>
</template>

<script>
export default {
name: 'App'
}
</script>

Step 3: Best Practices for Vue Beginners

  • Use single-file components (.vue) for better organization.

  • Leverage computed properties for derived state.

  • Use Vue Router for navigation.

Step 4: Common Vue Mistakes

  • Not using v-bind and v-model correctly.

  • Overusing watchers instead of computed properties.

  • Ignoring component reusability.

Step 5: Learning Resources for Vue

Section 3: Learning Angular

What is Angular?

Angular is a TypeScript-based framework maintained by Google, known for building large, scalable web applications.

Step 1: Setting Up Your First Angular App

npm install -g @angular/cli
ng new my-angular-app
cd my-angular-app
ng serve

Step 2: Your First Angular Component

typescript
import { Component } from '@angular/core';

@Component({
selector: 'app-root',
template: `
<h1>Hello Angular!</h1>
<p>Welcome to your first Angular app.</p>
`
})
export class AppComponent {}

Step 3: Best Practices for Angular Beginners

  • Use Angular CLI for generating components/services.

  • Structure code into modules for scalability.

  • Implement services for data management.

Step 4: Common Angular Mistakes

  • Skipping TypeScript benefits – Always type your variables.

  • Not using Angular CLI – Slows down development.

  • Poor file organization – Makes scaling harder.

Next Steps

Once you’ve tried all three, focus on one framework and master it.

  • If you love flexibility, pick React.

  • If you want simplicity, start with Vue.

  • If you prefer structure and TypeScript, go for Angular.
