Short answer: function Home() { return <h1>Home Page</h1>; } function About() { return <h1>About Page</h1>; }

Example code

function Home() { return <h1>Home Page</h1>;
} function About() { return <h1>About Page</h1>;
}

Real-world example (ShopNest)

ShopNest’s storefront is React: components for ProductCard, CartDrawer, and CheckoutForm, with hooks for local UI state.

Say this in the interview

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
