What is the difference between React Suspense and React Lazy?

React Suspense is a feature that allows you to wait for some code to load before rendering a component, while React Lazy is a function that lets you dynamically import components. They often work together.

Can you give me an example of how to use them together?

Sure! You can use React Lazy to load a component and wrap it in a Suspense component to show a fallback UI while it's loading. Here's a simple example:

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

<Suspense fallback={<div>Loading...</div>}>
  <LazyComponent />
</Suspense>

What are the benefits of using these features?

The main benefits are improved performance and user experience. By loading components only when needed, you reduce the initial load time and can show a loading state to keep users informed.

Are there any drawbacks to using them?

One drawback is that if not used carefully, it can lead to a more complex codebase. Additionally, if the loading time is too long, it might frustrate users.
