React Suspense vs Loading Indicators

What are the main differences between React Suspense and traditional loading indicators?

React Suspense is a feature that allows components to 'wait' for something before rendering, while loading indicators are visual cues that show the user that content is being loaded. Suspense can manage loading states more seamlessly within the component tree.

Can you give me an example of how to implement React Suspense?

Sure! You can use React's Suspense component to wrap your lazy-loaded components. For 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 advantages of using Suspense over loading indicators?

Using Suspense allows for a more integrated loading experience, as it can handle multiple asynchronous operations and manage loading states without needing to manually track them. This leads to cleaner code and better user experience.

Are there any limitations to using React Suspense?

Yes, React Suspense is primarily designed for data fetching and may not be suitable for all scenarios. It also requires the use of React 16.6 or later and may not work with all libraries.
