Introduction to React

What is React?

React is a JavaScript library for building user interfaces. It was developed by Facebook (Meta) and is now open-source, widely used in web development.

Why Use React?

  1. Component-Based Architecture – Build reusable UI components.
  2. Virtual DOM – Efficient updates for better performance.
  3. Declarative Syntax – Write cleaner and more readable code.
  4. Strong Community & Ecosystem – Large support with many libraries.
  5. Fast Learning Curve – Easy to get started, especially for JavaScript developers.

How React Works

  • React uses a Virtual DOM to optimize updates.
  • It breaks UI into components, which manage their own state.
  • React re-renders only the changed parts of the UI, improving performance.

Basic Example of React Component

import React from "react";

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

export default Greeting;
Enter fullscreen mode Exit fullscreen mode

When to Use React?

  • Single Page Applications (SPA)
  • Dynamic UI Updates (e.g., dashboards, social media feeds)
  • Reusable UI Components (e.g., design systems)
