What is React.lazy and Suspense?

Can you explain what React.lazy and Suspense are?

Sure! React.lazy is a function that allows you to load components lazily, meaning they are loaded only when needed. Suspense is a component that lets you handle the loading state while the lazy component is being fetched.

How do I use React.lazy in my project?

You can use React.lazy by importing it from React and wrapping your component import in a function. For example: const LazyComponent = React.lazy(() => import('./LazyComponent'));

What happens if the lazy component fails to load?

If the lazy component fails to load, you can use the fallback prop of the Suspense component to display a loading indicator or an error message.

Can I use multiple lazy components with Suspense?

Yes, you can wrap multiple lazy components in a single Suspense component, and it will handle the loading state for all of them.
