What are the best practices for memory management in React?

To manage memory effectively in React, consider using functional components, hooks, and the useEffect hook to clean up resources.

Can you explain how the useEffect hook helps with memory management?

Certainly! The useEffect hook allows you to perform side effects in function components. By returning a cleanup function, you can free up resources when the component unmounts or updates.

What are some common memory leaks in React applications?

Common memory leaks include not cleaning up subscriptions, timers, or event listeners in useEffect, and retaining references to unmounted components.

How can I detect memory leaks in my React app?

You can use the Chrome DevTools Performance tab to profile your app and look for unexpected memory growth over time.
