An example of an AI chatbot conversation about the useCallback hook in React.
What is the useCallback hook in React?
The useCallback hook is used to memoize functions in React, preventing unnecessary re-creations on re-renders.
Why is it important to use useCallback?
It's important because it helps optimize performance by avoiding unnecessary renders of child components that depend on the function.
Can you give me an example of how to use it?
Sure! Here's a simple example: const memoizedCallback = useCallback(() => { doSomething(); }, [dependency]);.
When should I avoid using useCallback?
You should avoid it when the performance gain is negligible, as it can add complexity to your code.
