What is code splitting and how can it improve my web app?

Code splitting is a technique that allows you to split your code into smaller chunks, which can be loaded on demand. This improves load times and performance.

Can you give me an example of how to implement code splitting in a React app?

Sure! In a React app, you can use React.lazy and Suspense to dynamically import components. For example:

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

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

What are the benefits of using code splitting?

The main benefits include faster initial load times, reduced bundle sizes, and improved user experience as users only load the code they need.

Are there any tools that can help with code splitting?

Yes! Tools like Webpack and Parcel have built-in support for code splitting, making it easier to manage your code chunks.
