Suspense is a feature in React that allows you to declaratively specify loading states and fallback content for asynchronous operations like data fetching or code splitting. It helps improve the user experience by providing a smoother loading experience.
Key points:
Declarative loading: Use Suspense to declaratively specify loading states.
Fallback content: Provide fallback content to display while data is loading.
Data fetching: Use Suspense with asynchronous operations like data fetching.
Code splitting: Combine Suspense with code splitting for better performance.
Example:
In this example, the LazyComponent is loaded lazily using lazy, and the Suspense component provides a fallback message while the component is loading.
