What are React Hooks and how do they work with Concurrent Mode?

React Hooks are functions that let you use state and other React features without writing a class. Concurrent Mode is a set of new features that help React apps stay responsive and gracefully adjust to the user’s device capabilities.

Can you give me an example of a React Hook?

Sure! One common example is the useState hook, which allows you to add state to functional components. For instance, you can use it like this: const [count, setCount] = useState(0);.

How does Concurrent Mode improve performance?

Concurrent Mode allows React to work on multiple tasks at once, making it more efficient. It can pause, abort, or restart rendering work, which helps keep the app responsive even during heavy computations.

Are there any downsides to using Concurrent Mode?

Yes, while Concurrent Mode can improve performance, it may introduce complexity in your code. Some libraries may not be compatible, and debugging can be more challenging.
