useEffect runs after every render by default. Here's how to control it: ✅ Run once on mount: useEffect(() => { ... }, []) ✅ Run when a value changes: useEffect(() => { ... }, [value]) ✅ Cleanup on unmount: useEffect(() => { return () => cleanup() }, []) One hook. Three behaviors. Know the difference. 🎯 #ReactJS #Frontend #JavaScript #WebDev

Your website might be slow… and heavy JavaScript could be the reason. Large scripts block rendering and delay interaction. 👉 Less code = better performance #WebsiteSpeed #WebPerformance #JavaScript #PageSpeed #TechnicalSEO #WebDevelopment #Optimization #CoreWebVitals #Frontend #DigitalGrowth

What is a Component? A reusable building block of a user interface. 🔹 Functional Components ⚡ ✔ Simple & easy to write ✔ Use Hooks (useState, useEffect) ✔ Preferred in modern React 🔹 Class Components 🏗 ✔ Uses lifecycle methods ✔ More complex structure ✔ Mostly replaced by Hooks 🔹 Why Components Matter? 🔁 Reusable code 📂 Organized structure 🚀 Faster development #ReactComponents #ReactJS #FrontendDevelopment #JavaScript

🚀 💡 JavaScript Tricky Question Explanation const arr = [4, 10, 2, 8]; const result = arr.find(num => num > 5) + arr.findIndex(num => num > 5); console.log(result); 👉 Output: 11 👉 Explanation: * find() returns the first value > 5 → `10` * findIndex() returns its index → `1` * Final result → `10 + 1 = 11` ⚡ Both stop at the **first match** #JavaScript #WebDevelopment #Frontend #CodingInterview #JSConcepts
