What is the difference between useCallback and useMemo in React?
An example of an AI chatbot conversation about useCallback and useMemo in React.
Can you explain the difference between useCallback and useMemo in React?
Sure! useCallback is used to memoize functions, while useMemo is used to memoize values. They help optimize performance.
When should I use useCallback instead of useMemo?
You should use useCallback when you want to prevent a function from being recreated on every render, especially when passing it to child components.
Can you give me an example of when to use each?
Absolutely! Use useCallback for event handlers and useMemo for expensive calculations that you want to cache.
Are there any performance implications of using them?
Yes, using them unnecessarily can lead to performance overhead. It's best to use them only when needed.
