React Performance Cheat Code:
useCallback vs useMemo
Your React app feels slow ❓
Because everything is re-rendering again & again 👀
📌 useCallback 👉 Memoizes FUNCTION ✔ Prevents function re-creation on every render
✔ Best when passing callbacks to child components
📌 useMemo 👉 Memoizes VALUE ✔ Prevents expensive recalculations
✔ Best for heavy computations
🧠 Simple rule to remember
Function reference issue ❓ ➜ useCallback
Expensive calculation ❓ ➜ useMemo
⚠️ Don’t optimize blindly
Measure first, then memoize.
🔥 Clean code + smart memoization = FAST React apps

🔥 Types of APIs Every Developer MUST Know 🚀
If you want to survive (and grow) as a developer in 2026, these APIs are non-negotiable 👇
🔹 REST API – Backbone of modern web & mobile apps
🔹 GraphQL API – Fetch exactly what you need, nothing extra
🔹 SOAP API – Still used in banking & enterprise systems
🔹 WebSocket API – Real-time features like chat & live updates
🔹 Third-Party APIs – Payments, Maps, Auth, Notifications
🔹 Browser APIs – LocalStorage, Geolocation, Clipboard
🔹 Internal APIs – Power microservices & backend communication
👉 Mastering APIs = Faster apps + Better architecture + Higher salary 💰
APIs are not just “backend stuff” anymore — every frontend dev must know this.
