How do you pass parameters in routes?

Short answer: You can pass URL parameters (also called dynamic routes) using : in the route path. Example: import { BrowserRouter as Router, Route, Switch, useParams } from 'react-router-dom'; function App() { return ( <Router> <Switch> <Route path="/user/:id" component={User} /> </Switch> </Router> ); } function User() { const { id } = useParams(); // Access the dynamic parameter

Example code

return <h1>User ID: {id}</h1>;
} In the example above, visiting /user/1 will display User ID: 1.

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

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
