An example of an AI chatbot conversation about common mistakes with useLayoutEffect in React.
What are the common mistakes when using useLayoutEffect in React?
Some common mistakes include using it for side effects that don't need to block the browser's painting, or forgetting to clean up.
Can you explain why it's important to clean up in useLayoutEffect?
Cleaning up prevents memory leaks and ensures that effects don't run unnecessarily, which can lead to performance issues.
What are some scenarios where I should prefer useEffect over useLayoutEffect?
You should prefer useEffect for asynchronous operations or when you don't need to block the browser's painting.
How does useLayoutEffect differ from useEffect in terms of timing?
useLayoutEffect runs synchronously after all DOM mutations, while useEffect runs asynchronously after painting.
