What is the difference between React Concurrent Rendering and Suspense?

React Concurrent Rendering allows React to work on multiple tasks simultaneously, improving performance. Suspense, on the other hand, is a feature that lets you wait for some code to load before rendering a component, enhancing user experience.

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

Sure! You can use Suspense by wrapping your lazy-loaded components with the <Suspense> component and providing a fallback UI. For example:

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

How does Concurrent Rendering improve performance?

Concurrent Rendering improves performance by allowing React to pause work and come back to it later, prioritizing more important updates. This means smoother interactions and less blocking during rendering.

Are there any downsides to using these features?

Yes, while they offer great benefits, they can also introduce complexity in your codebase and may require a learning curve to implement effectively.
