What is React Lazy and how do I use it?

What is React Lazy and how can I implement it in my project?

React Lazy is a feature that allows you to load components lazily, which means they are only loaded when needed. You can implement it using React.lazy() and Suspense.

Can you show me a code example of how to use React Lazy?

Sure! Here's a simple example:

import React, { Suspense, lazy } from 'react';

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

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

What are the benefits of using React Lazy?

The main benefits include improved performance by reducing the initial load time and better user experience as components load only when required.

Are there any drawbacks to using React Lazy?

Yes, one drawback is that it can complicate error handling and loading states, as you need to manage these for lazy-loaded components.
