Frontend Optimization Techniques You Need to Know! Frontend performance is not just about reducing bundle size or lazy loading. Here are some lesser-known but highly effective techniques to improve rendering speed and user experience: 🔹️ CSS Containment (contain) - Limits rendering scope for efficient updates. 🔹️ Preloading - Prioritizes critical assets for faster load times. 🔹️ Async Image Decoding (decoding="async") - Prevents layout blocking. 🔹️ Content-Visibility (content-visibility: auto) - Skips rendering offscreen elements. 🔹️ WebP & AVIF - Optimized image formats for reduced file size.

6 Years of React – 5 Hard-Earned Lessons Working on large-scale React apps taught me things no tutorial ever did. Here are 5 lessons I learned the hard way 👇 🔹 1. Reusability is gold, but over-abstraction is a trap. Reusable components are great — but if no one understands them, they’re a liability. Keep it simple and readable. 🔹 2. Performance optimization ≠ useMemo everywhere. Identify actual bottlenecks using tools like React Profiler, Lighthouse, and Chrome DevTools. Optimize with intent. 🔹 3. Folder structure matters more than you think. A clean, scalable architecture saves hours in debugging, onboarding, and scaling. 🔹 4. Choose the right state management tool. Context API is perfect for lightweight needs. Redux or Zustand shine in complex apps — know when to use what. 🔹 5. Communication beats code. Writing clean PRs, syncing early with backend, and updating your team regularly adds more value than just pushing features. 💬 What’s one lesson React has taught you that no tutorial did?

#JavaScript Event Loop 👇 JS runs single-threaded, but async tasks use the Web APIs and come back later through the Callback Queue – only when the Call Stack is clear! What actually happens: 1. console.log(“Start”) is added to the Call Stack and gets executed → prints Start. 2. Next, setTimeout(...) is encountered. • JS moves this to the Web APIs (like the browser’s timer). • Even though the delay is 0ms, it’s asynchronous, so the callback is offloaded. 3. console.log(“End”) is added to the stack and executed → prints End. 4. After 0ms, the callback from setTimeout moves to the Callback Queue. 5. Only when the Call Stack is empty, the Event Loop pushes the callback to the stack → prints Timeout. #webdev #frontenddev #learntocode #javascript #reactjs

Why Frontend Developers Should Care About API Rate Limiting !! Imagine this: You’re at a buffet, but the waiter says – “Only 2 plates per person per hour.” That’s API rate limiting in real life. In frontend apps, ignoring rate limits = frustrated users, failed requests, and messy UI states. Here’s how I handle it: Show meaningful errors: “Too many requests, try again in 1 min.” Retry with backoff: Instead of spamming requests, wait longer after each fail. Cache responses: Don’t ask the server for what you already know. Frontend isn’t just about pixels. It’s about handling the invisible rules of the web too.
