What are the differences between React 18's Suspense and earlier versions?

React 18 introduces a more powerful Suspense feature that allows for better handling of asynchronous data fetching. Unlike previous versions, it supports concurrent rendering, which improves user experience by allowing components to load in a more fluid manner.

Can you explain how concurrent rendering works with Suspense?

Sure! Concurrent rendering allows React to work on multiple tasks at once. With Suspense, it can pause rendering while waiting for data, and then resume once the data is ready, making the UI more responsive.

What are some practical use cases for using Suspense in React 18?

Some practical use cases include loading data for components, code-splitting to reduce initial load times, and managing loading states for images or other resources.

Are there any drawbacks to using Suspense?

One potential drawback is that it can add complexity to your codebase, especially if you're not familiar with concurrent features. Additionally, it may require updates to existing components to fully leverage its capabilities.
