What is React Suspense and how does it work?

React Suspense is a feature that allows you to wait for some code to load before rendering a component. It helps in managing asynchronous operations.

Can you give me an example of how to use it?

Sure! You can use the <Suspense> component to wrap your lazy-loaded components. For example:

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

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

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

What does the fallback prop do?

The fallback prop specifies what to render while the lazy component is loading. It's a way to provide a loading indicator.

Are there any limitations to using React Suspense?

Yes, React Suspense is primarily designed for data fetching and code splitting. It may not work seamlessly with all libraries or in all scenarios.
