What is React lazy function?

The React.lazy function lets you render an dynamic import as a regular component. It will automatically load the bundle containing the OtherComponent when the component gets rendered. This must return a Promise which resolves to a module with a default export containing a React component.

const OtherComponent = React.lazy(() => import('./OtherComponent'));
function MyComponent() {
return (
<div>
<OtherComponent />
</div>
);
}

Note: React.lazy and Suspense is not yet available for server-side rendering. If you want to do code-splitting in a server rendered app, we still recommend React Loadable.
