Structuring React Packages for Harder Development

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

Closures are one of those JavaScript concepts that feel confusing at first, but once you understand them, a lot of things start making sense. #javascript #frontend

🧠 React Hook Lifecycle Quiz Can you predict the output and explain why? 👇 🔹 Phase 1: Initial Mounting - What will be logged on the first render? 🔹 Phase 2: Updating (when clicking incrementCount) - What will be logged after clicking the button? #ReactJS #Frontend #WebDevelopment #JavaScript #ReactHooks #NextJS

I built the same simple form in two ways: - React Hook Form + MUI → 136 lines - Dashforge → 74 lines Same result. This is a simple case… imagine when it gets complex. Curious to hear how others are handling forms in React. #react #reacthookform #mui #frontend #webdevelopment #javascript #typescript #developerexperience

just published part 2 of my React internals series , this one covers what actually happens when you call setState and how does re-rendering works. part 1 (initial render): https://lnkd.in/dycpqavw part 2 (re-render): https://lnkd.in/d4tWTwmk #react #javascript #frontend #webdev

JavaScript Event Loop The event loop is a system that decides: - What code runs now - What runs later 👉 Sync → Microtasks(Promise.then, async/await) → Macrotasks(setTimeout, setInterval) Example below: A F H C E G D B 🎯 If you understand WHY this happens, you really understand the event loop. #javascript #webdev #frontend #async

Svelte vs Traditional Frameworks Most frameworks push heavy work to the browser, increasing runtime cost and slowing down performance. Svelte takes a different approach — it shifts that work to compile time, producing highly optimized vanilla JavaScript. The result: faster load times, smoother runtime performance, and minimal browser overhead. Sometimes, the best optimization is doing less in the browser.   #Svelte #WebDevelopment #JavaScript #Frontend #WebPerformance #SoftwareEngineering #Ziplink

You’re using useEffect WRONG ⚠️ Most React developers make this mistake daily. useEffect is NOT for everything. Here’s where most devs go wrong: ❌ Using it for derived state ❌ Using it for simple calculations Instead: ✔ Compute values during render ✔ Keep logic simple Have you made this mistake before? Comment YES if you have 👇 #ReactJS #Frontend #WebDevelopment #JavaScript #CleanCode

🚀 💡 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
