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>

What are the benefits of using code splitting?

Code splitting improves load times by reducing the initial bundle size, allowing users to download only the code they need for the current view.

Are there any downsides to using lazy loading?

Yes, lazy loading can lead to a delay in rendering components, which might affect user experience if not implemented carefully.
