React has become one of the most popular JavaScript libraries for building user interfaces. In this post, we'll explore the fundamentals and best practices.

Why React?

React offers several advantages:

• Component-Based Architecture - Build encapsulated components that manage their own state
• Virtual DOM - Efficient updates and rendering
• Rich Ecosystem - Extensive libraries and tools
• Strong Community - Active community and support

Getting Started

First, you'll need to set up your development environment:

npm create vite@latest my-react-app -- --template react-ts
cd my-react-app
npm install
npm run dev

Your First Component

Here's a simple React component:

function Welcome({ name }: { name: string }) {
  return <h1>Hello, {name}!</h1>;
}

export default Welcome;

State Management

React provides hooks for managing state:

import { useState } from "react";

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <p>Count: {count}</p>
      <button onClick={() => setCount(count + 1)}>Increment</button>
    </div>
  );
}

Conclusion

React is a powerful tool for building modern web applications. Start with the basics and gradually explore more advanced concepts like context, reducers, and custom hooks.
