How do you combine Suspense with React Router?

Combining React's Suspense with React Router can significantly enhance the user experience by allowing you to manage loading states effectively while navigating between different routes. This approach is particularly useful when dealing with code-splitting and lazy loading components, as it provides a seamless way to handle asynchronous operations.

To implement Suspense with React Router, you need to ensure that your components are set up to be lazy-loaded. This can be achieved using React's `React.lazy()` function, which allows you to dynamically import components. Below, I will outline the steps to combine these two powerful features, along with best practices and common pitfalls to avoid.

Setting Up Lazy Loading with React.lazy()

First, you need to import the components you want to lazy-load using the `React.lazy()` function. Here’s a simple example:

import React, { Suspense, lazy } from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

const Home = lazy(() => import('./Home'));
const About = lazy(() => import('./About'));
const NotFound = lazy(() => import('./NotFound'));

Using Suspense with React Router

Once you have your components set up for lazy loading, you can wrap your routes with the `Suspense` component. This allows you to specify a fallback UI that will be displayed while the lazy-loaded component is being fetched. Here’s how you can do it:

function App() {
  return (
    
      Loading...
