How can I optimize the useState hook in React?

To optimize useState, consider using functional updates and batching state updates to reduce re-renders.

What are functional updates?

Functional updates allow you to pass a function to setState, which receives the previous state as an argument.

Can you give me an example of using functional updates?

Sure! Instead of setCount(count + 1), you can use setCount(prevCount => prevCount + 1). This is more efficient.

Are there any performance concerns with useState?

Yes, excessive state updates can lead to performance issues. Use memoization techniques like useMemo or useCallback to mitigate this.
