💡 Mini-Tip #20 — Real Project Talk

Always link your answer to a story:
🗣️ “We reduced re-renders by 40% using memoized selectors in Redux Toolkit.”
Numbers + Impact = Confidence.

🌿 Mini-Tip #19 — Error Boundaries

In interviews, mention how you handle crashes.
✅ Use componentDidCatch or error boundary components — it shows production mindset.

🚀 Mini-Tip #18 — Lazy Loading Wins

Break bundles with React.lazy() & Suspense.
Faster initial load = happier users.

💬 Mini-Tip #17 — Real-World Question

Q: “Your React app lags — how do you debug?”
A: Start with React Profiler → check render counts → identify heavy components → memoize or split code.

🌈 Mini-Tip #16 — Component Design

Think in composition, not inheritance.
🧩 Reuse logic via hooks, reuse UI via children props.

🔄 Mini-Tip #15 — useCallback Wisdom

If you pass functions to child components — wrap them in useCallback.
Stable references = fewer re-renders.

🧠 Mini-Tip #14 — Avoid Over-Rendering

Wrap components with React.memo only when props rarely change.
Otherwise, memoization = wasted CPU cycles.

🌿 Mini-Tip #13 — useRef Power Move

useRef isn’t just for DOM access — it also stores mutable values without re-renders.
Great for timers, prev values, or caching.
