What are React's concurrent features and how do they work?

React's concurrent features allow for more responsive user interfaces by enabling React to work on multiple tasks at once. This means that React can pause, abort, or restart rendering work as needed, improving the overall user experience.

Can you explain how concurrent rendering improves performance?

Concurrent rendering improves performance by allowing React to prioritize updates. It can split rendering work into chunks, so the app remains responsive even during heavy updates.

What are some examples of concurrent features in React?

Some examples include Suspense for data fetching, automatic batching of updates, and transitions that allow for smoother state changes.

How do I enable concurrent features in my React app?

To enable concurrent features, you need to use React 18 or later and wrap your app in the <ConcurrentMode> component. You can also use the new APIs like startTransition for transitions.
