⚛️ Top 150 React Interview Questions – 54/150 📌 Topic: useMemo vs. useCallback 🔹 WHAT is it? useMemo → Remembers a value (the answer to a heavy calculation) useCallback → Remembers a function (the way to do something) 🔹 WHY use them? useMemo Stops React from doing the same heavy work (like sorting or filtering) again and again. useCallback Stops React from re-creating functions on every render, which helps prevent unnecessary re-renders. 🔹 HOW do you use them? useMemo (The Value) const result = useMemo(() => heavyMath(data), [data]); useCallback (The Action) const handleClick = useCallback(() => doSomething(), []); 🔹 WHERE / Best Practices ✔ Use useMemo for slow or expensive calculations ✔ Use useCallback when passing functions to child components ⚠️ Rule of Thumb Don’t use them for simple things. It’s like using a safe for a candy bar 🍬 — not worth the effort. 📝 Summary (Easy to Remember) useMemo is like a Post-it note 📝 with the answer written on it. useCallback is like a video recording 🎥 showing how to do a task. 👇 Comment “React” if this series is helping you 🔁 Share with someone preparing for React interviews #ReactJS #ReactInterview #FrontendDevelopment #JavaScript #ReactHooks #useMemo #useCallback #Top150ReactQuestions #LearningInPublic #Developers
