🚀 React State Updates 🚀 Why console.log “lies” after setState (and how to fix it!) 👀 A common React trap: When you call setState, React doesn’t update immediately — it schedules the update. That’s why logging right after shows the old value. ⚡ Key points: 🔹 setState is async — updates happen in the next render cycle. 🔹 React batches updates for performance, so the change isn’t visible right away. 🛠️ Pro Tip: If your update depends on the previous state, always use the functional form: setState(prev => newValue) ✅ This guarantees correctness, no matter how React batches updates. 👇 Have you ever been confused by React’s async state updates? #React #TypeScript #NextJS #FrontendTips #WebDev #DevProductivity #CodingTips #DeveloperExperience

🔄 Why does your useEffect keep running endlessly? 🤔 At first, your code looks fine… but there’s a hidden trap: ❌ Objects, arrays, and functions aren’t like primitives. Every render creates a new reference, so React thinks the dependency changed—even if the content is identical. The result? Your effect keeps firing on repeat. ✅ The fix: memoization (useMemo or useCallback). With stable references, React only reruns the effect when it actually should. 🔧 How I avoid the trap: 👉 Remember: non-primitives are passed by reference, not by value. 👉 Memoize values/functions when including them in dependency arrays. 👉 Move them outside the render if they don’t depend on props or state. ⚡ Stable references = fewer re-renders + fewer bugs. 🚀 👇 What’s the most common useEffect gotcha you run into? #React #TypeScript #JavaScript #WebDevelopment #FrontendDevelopment #Coding #TechCommunity #ReactJS #WebDev #FullStackDevelopment #TechTrends
