How can I optimize performance in my React app using TypeScript and hooks?

You can optimize performance by using memoization with useMemo and useCallback, and by minimizing re-renders.

What is memoization and how does it help?

Memoization is a technique to cache results of expensive function calls. It helps by preventing unnecessary recalculations.

Are there any specific hooks I should avoid for performance?

Avoid using useEffect for heavy computations directly; instead, offload them to web workers or use useMemo.

Can you give an example of using useMemo?

Sure! You can use useMemo to cache a computed value like this: const memoizedValue = useMemo(() => computeExpensiveValue(a, b), [a, b]);.
