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 path="/about" component={About} />
</Switch>
</Router>
);
}
