Key React Features

1. JSX: JavaScript Syntax Extension

React uses JSX to mix HTML with JavaScript:

javascript
function Welcome() {
  return <h1 id="Hello-React">Hello, React!</h1>;
}
2. State Management with Hooks
React’s useState and useEffect simplify state management:

javascript
Copy code
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>
  );
}
3. Routing with React Router
Add navigation to your app:

javascript
Copy code
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

function App() {
  return (
    <router>
      <switch>
        <route path="/" exact component="{Home}"></route>
        <route path="/about" component="{About}"></route>
      </switch>
    </router>
  );
}
