What is the difference between lazy loading and code splitting in React?

Lazy loading is a technique to load components only when they are needed, while code splitting divides your code into smaller chunks that can be loaded on demand.

Can you give me an example of how to implement lazy loading in a React app?

Sure! You can use React's React.lazy and Suspense to implement lazy loading. For example:

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

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

How does code splitting improve performance?

Code splitting improves performance by reducing the initial load time of your application. It allows users to download only the necessary code for the current view, rather than the entire application upfront.

Are there any downsides to using lazy loading?

Yes, potential downsides include increased complexity in your code and the possibility of a delay in loading components, which can affect user experience if not handled properly.
