How can I design a custom 404 page using React Router v6?

To design a custom 404 page in React Router v6, you can create a new component for your 404 page and use the Route component to render it when no other routes match.

Can you show me a code example?

Sure! Here's a simple example:

import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import NotFound from './NotFound';

function App() {
  return (
    <Router>
      <Routes>
        {/* Other routes */}
        <Route path='*' element={<NotFound />} />
      </Routes>
    </Router>
  );
}

In this example, the NotFound component will be displayed for any unmatched routes.

What should I include in my 404 page?

Your 404 page should include a friendly message, a search bar, and links to popular pages or the homepage to help users navigate.
