How can I implement a fallback UI in React Router?

You can implement a fallback UI in React Router by using the Suspense component along with React.lazy for code splitting.

Can you show me a code example?

Sure! Here's a simple example:

import React, { Suspense, lazy } from 'react';

const LazyComponent = lazy(() => import('./LazyComponent'));

function App() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <LazyComponent />
    </Suspense>
  );
}

What if the component takes too long to load?

You can customize the fallback UI to show a loading spinner or a message indicating that the content is loading.

Is there a way to handle errors during loading?

Yes, you can use error boundaries to catch errors in your lazy-loaded components and display an error message.
