When should I use lazy loading in React?

You should use lazy loading in React when you want to improve performance by loading components only when they are needed.

Can you give me an example of how to implement lazy loading?

Sure! You can use React's React.lazy and Suspense to lazy load components. Here's a simple example:

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

function App() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <LazyComponent />
    </Suspense>
  );
}

What are the benefits of using lazy loading?

The benefits include faster initial load times, reduced bundle size, and improved user experience as components load on demand.

Are there any downsides to lazy loading?

Yes, potential downsides include increased complexity in your code and possible delays in rendering components that are lazy-loaded.
