React

🔹 What is React?

React is a free and open-source JavaScript library developed by Meta (formerly Facebook) for building user interfaces (UI), especially for single-page applications (SPAs).

React lets developers create reusable components, manage UI efficiently, and build fast, scalable web apps.

🔹 Key Features of React

1. Component-Based Architecture

   • Breaks UI into reusable pieces (components)

   • Promotes modular and clean code

2. JSX (JavaScript XML)

   • Allows writing HTML in JavaScript

   • Makes code more readable and easier to debug

3. Virtual DOM

   • Optimizes rendering by updating only parts of the DOM

   • Leads to faster performance

4. One-Way Data Binding

   • Ensures data flows in a single direction

   • Makes it easier to debug and maintain

5. Hooks (React 16.8+)

   • Use state and lifecycle methods in functional components

   • Examples: useState, useEffect, useContext

6. React Router

   • For routing in single-page applications

   • Enables navigation without refreshing the page

🔹 Advantages of React

✅ Fast rendering with Virtual DOM
✅ SEO-friendly (with tools like Next.js)
✅ Huge community and ecosystem
✅ Easy to integrate with other frameworks
✅ Widely used in web and mobile apps (React Native)

🔹 Popular Use Cases
