Server Components are a game-changer for React applications. They allow you to render components on the server, reducing the JavaScript bundle size sent to the client.

// Server Component (default in App Router)
async function ProductList() {
  const products = await fetch('https://api.example.com/products');
  return <div>{/* render products */}</div>;
}
