What is React Suspense?
Suspense allows developers to display a temporary fallback UI when the component is doing the asynchronous operation. When the operation is completed, the actual UI is rendered. Suspense can be used when a child component is lazily loaded or fetching data.
Syntax:
<Suspense fallback={<div>Loading...</div>}>
<AsyncComponent /> //ChildComponent
</Suspense>
- children: The actual UI that you intend to render
- fallback: An alternate UI if actual UI is loading.
How does Suspense help in Handling Asynchronous Operations in React ?
Suspense, first introduced in React 16, is a feature that aims to enhance the user experience by managing asynchronous operations. It simply lets you render a fallback UI decoratively while the child component is waiting for any asynchronous task to be completed.
