Q78: What is React Router? - React & Modern Frontend (445 Qs)

React Router is a powerful routing library built on top of React that helps you add new screens and flows to your application incredibly quickly, all while keeping the URL in sync with what's being displayed on the page.

Practical Code Example

jsx

// React Router: Client-side routing library for Single Page Applications
import { BrowserRouter, Routes, Route, Link } from 'react-router-dom';

function App() {
  return (
    <BrowserRouter>
      <nav><Link to="/">Home</Link> | <Link to="/about">About</Link></nav>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="/about" element={<About />} />
      </Routes>
    </BrowserRouter>
  );
}
