Next.js 16 Released with Turbopack and React 19 Support

React Closures and State Updates Let’s say we start with: const [value, setValue] = useState(0) Now imagine we run this: setValue(value + 1) setValue(prev => prev + 2) • What is the final value? Now another scenario: setValue(prev => prev + 2) setValue(value + 1) • And now, what is the final value? This happens because React batches updates and functions keep the value they captured earlier. Mixing value + 1 with prev => prev + X can lead to unexpected results. Understanding how React handles state updates makes your code more predictable. What do you think the final values are? #React #JavaScript #Frontend

React Server Components are no longer “the future”. They’re the present. If you’re using modern frameworks like Next.js, you’re already working with them — sometimes without realizing it. What changed my mindset: - Less JavaScript sent to the client - Faster initial loads - Clear separation between server logic and UI The real challenge isn’t using RSC. It’s thinking differently about where your code should run. 💡 Tip: stop asking “Can this run on the client?” Start asking “Does this even need to?” #react #nextjs #webperformance #frontend #javascript

One Next.js concept that confuses almost everyone 🤯 If components are server-side by default, why do we still write use server? The answer is simple: UI rendering and server logic are two different things. Did this confuse you before? 👇 Share your thoughts in the comments #NextJS #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #ServerComponents #ServerActions #ProgrammingReels #DevCommunity #LearnToCode

React Server Components fundamentally reshape our client-server paradigm. It's more than a new API. The biggest win I've seen in production isn't just smaller bundles. It's keeping data-intensive logic and API calls EXTREMELY close to the source, slashing initial load times. But here's the kicker: mismanaging the client-server boundary means subtle serialization issues and client-side waterfalls you thought you eliminated. A clear understanding of "use client" boundaries is CRITICAL. Embrace the server-first mindset and explicitly define your boundaries. It PAYS OFF. #React #Frontend #WebPerformance #RSC #JavaScript

Stop reinventing the wheel. 🛑 The React and Next.js ecosystem is massive, and choosing the right stack can be paralysing. I’ve put together a visual guide to the essential libraries that are standardising modern web development. From styling with Tailwind to state management with Zustand, these are the tools that help you ship faster and write cleaner code.

🚀 A tiny React trick that solves a very real problem Imagine a user clicks “Pay Now” twice 😅 → API runs twice → order created twice → payment deducted twice 💸 So I made a small hook useSafeAsync: 🛑 stops multiple clicks ⏳ shows loading while API runs ✅ shows success after response ❌ shows error if request fails ⏱️ auto-stops if server hangs (timeout) It uses AbortController to cancel stuck requests and bring the UI back to normal. Small code… but it can prevent many headaches (and angry users) 😄 #reactjs #javascript #frontend #webdevelopment #codingtips #typescript

5 React.js Performance Optimization Techniques I Use on Every Project Code splitting with React.lazy() → Reduces initial bundle size by 40-60% Memoization (useMemo, React.memo) → Prevents unnecessary re-renders Virtual scrolling for large lists → Handles 10K+ items smoothly Debouncing expensive operations → Saves thousands of API calls Bundle size analysis → Catches bloat before production Performance isn't a feature—it's a requirement. Save this for your next optimization sprint! 📌 #ReactJS #WebPerformance #FrontendDevelopment #JavaScript

Most React devs overuse useState in forms and pay the price in performance Here’s when to stop, and what to use instead For more information contact : https://lnkd.in/gNan5xMQ #React #WebDevelopment #Frontend #JavaScript #ReactHooks #CleanCode #DeveloperTips #CrystalZenTechnology

Today I explored Form Handling & Routing in React. Key takeaways: Managing form state with useState Implementing basic form validations Navigating between pages using BrowserRouter Building forms that actually validate and route correctly feels like a big step toward real-world applications.
