Create a Lazy Component

In order to use React Lazy Loading and Suspense, you need to create a lazy component. This is done by using the React.lazy() method. This method takes a function as an argument that must return a Promise which resolves to a module with a default export containing a React component. The code below shows an example of how to create a lazy component:

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

Once you have created the lazy component, you can then wrap it with the React.Suspense component. This will allow you to show a fallback component while the lazy component is loading. For more information on how to use React Lazy Loading and Suspense, please refer to the official React documentation.

Wrap the Lazy Component with Suspense

Once you have created a lazy component, you need to wrap it with the React.Suspense component. This component allows you to specify what should be displayed while the lazy component is loading. To do this, you need to import the React.Suspense component from the React library. You can do this by adding the following line of code to the top of your file:

import { Suspense } from 'react';

Once you have imported the React.Suspense component, you can wrap your lazy component with it. To do this, you need to add the following line of code to your file:

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

The fallback prop is used to specify what should be displayed while the lazy component is loading. In this example, we are displaying a div with the text "Loading...". Once you have wrapped your lazy component with the React.Suspense component, you can use it in your application.
