Optimize React Renders with Correct Reconciliation Algorithm

Built a Todo App using React + Context API! This project focuses on managing global state without external libraries. Users can add, update, and delete todos while the state is shared across components using the Context API. Highlights: 🔹 Add / Edit / Delete Todos 🔹 Global State Management with Context API 🔹 Clean Components & UI 🔹 React Hooks for Logic & Updates This project helped me improve my understanding of state sharing, component communication, and React architecture patterns. gitHub Repo : https://lnkd.in/dnQkfKqA #React #ContextAPI #JavaScript #WebDevelopment #Frontend #StateManagement #Developer #Coding #Projects #LearningInPublic #ReactJS #Programming #BuildInPublic #100DaysOfCode #CodeNewbie

React hooks are game changers, yaar! But one thing I see developers doing wrong is creating too many useState hooks when they could use useReducer. If you have 3+ related state variables that change together, useReducer is your friend. It keeps your logic organized and makes testing easier. Plus, it's more predictable when state updates get complex. Remember: useState for simple state, useReducer for complex state logic. Don't overcomplicate simple things, but don't undercomplicate complex ones either. Balance is key! What's your go-to approach for managing state?

🚀 New Article Live: React Hooks Explained (The Right Way) Most React articles teach syntax. This one focuses on thinking in hooks. I just published a deep dive on React Hooks, covering: Why hooks actually changed React How to structure cleaner, scalable components Practical patterns that work in real projects (not demos) Common mistakes I see developers repeat The goal: clarity over complexity. If you’re learning React or already building production apps, this should be useful. Would genuinely love feedback from the community. More structured, developer-first content coming soon. 💙 #React #JavaScript #WebDevelopment #Frontend #SoftwareEngineering #LearningInPublic #BuildInPublic #Developers #Programming #Tech Mahima Hans Codex Playground

#Day17 of my fifth #100CodingDays Today, I am sharing three exciting React projects: 1. Name Generator: A React app that generates names based on user input using the startup-name-generator library. It displays the generated names with links to check domain availability on Namecheap. 2. Lyrics Finder: A React app that fetches lyrics from the Lyrics.OVH API based on artist and song name. It displays the lyrics in a preformatted text block and handles loading state and errors. 3. QR Code Generator: A React app that generates QR codes based on user input using the QRCode library. It allows users to download the QR code and copy the text to the clipboard. #React #JavaScript #WebDevelopment #Coding #100DaysOfCode #FrontendDevelopment #WebDesign #Programming #DeveloperLife #CodingCommunity #Tech #Innovation #DigitalTransformation #SoftwareDevelopment #WebApp #ReactJS #APIIntegration #QRCode #LyricsFinder #NameGenerator #100DaysofCoding GitHub Link :- https://lnkd.in/gQfEVdfx

Discover the significant features of React JS!

React Hooks are a total game-changer for building modern interfaces! By allowing you to use state and other React features without writing class components, Hooks like useState and useEffect make your code significantly cleaner, more readable, and easier to test. They encourage functional programming patterns and allow you to extract component logic into reusable functions, which speeds up development and reduces boilerplate. Whether you’re managing complex API calls or simple form inputs, mastering Hooks is essential for any developer looking to build scalable, high-performance applications in the React ecosystem. #ReactJS #WebDevelopment #Coding #Hooks #JavaScript #Frontend #SoftwareEngineering #TechTips #ReactHooks #Programming

How react handles batch processing: I used to think every setState triggers a re-render. React is smarter than that. 👇 When multiple state updates happen in the same event loop tick, React often batches them. So if you do: setA(a + 1); setB(b + 1); setC(c + 1); React doesn’t render 3 times. It groups them into one update and does a single render Why this matters Better performance as fewer renders So, If your next state depends on previous state, prefer the functional form: setA(prev => prev + 1); Because batching can make a stale inside the same cycle. #React #JavaScript #Frontend #WebDevelopment #ReactJS #Performance #SoftwareEngineering #Programming #WebDev

𝗪𝗵𝘆 𝗜 𝗦𝘁𝗼𝗽𝗽𝗲𝗱 𝗔𝗱𝗱𝗶𝗻𝗴 𝗥𝗲𝗮𝗰𝘁 𝗟𝗶𝗯𝗿𝗮𝗿𝗶𝗲𝘀 𝗯𝘆 𝗗𝗲𝗳𝗮𝘂𝗹𝘁 Here’s the thing: more libraries do not automatically make an app better. For a long time, I added React libraries out of habit. If a problem existed, a package solved it. That approach looked fast, but it came with hidden costs. 𝗪𝗵𝗮𝘁 𝘁𝗵𝗶𝘀 𝗿𝗲𝗮𝗹𝗹𝘆 𝗺𝗲𝗮𝗻𝘀 𝗶𝘀 𝘀𝗶𝗺𝗽𝗹𝗲:  • More dependencies = more updates to track  • Bigger bundle size and slower load times  • Harder debugging when things break  • Less control over how the app behaves Now, I pause before adding anything new. If React or plain JavaScript can handle it cleanly, I keep it simple. If a library truly saves time, improves clarity, or avoids real complexity, I use it on purpose. Fewer dependencies. Clearer code. Easier maintenance. That tradeoff has been worth it. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #CleanCode #SoftwareEngineering #FrontendEngineer #DeveloperMindset #TechDecisions #CodeQuality #ReactDeveloper #Programming #BuildInPublic #DevBestPractices #ScalableApps #MaintainableCode #Engineering #ProductEngineering #WebApps #ModernWeb #DeveloperLife #CodingTips #TechThoughts #StartupTech #OpenSource #UIEngineering #SoftwareDevelopment #TechCommunity

⚡ Most React performance bugs aren’t caused by “slow code”. They’re caused by unnecessary re-renders. And most devs don’t even notice them. ━━━━━━━━━━━━━━━━━━━━━━━ The pattern I keep seeing: const Component = () => { const handleClick = () => { console.log("clicked"); }; return <Button onClick={handleClick} />; }; Looks innocent. Works perfectly. But here’s the hidden cost 👇 ━━━━━━━━━━━━━━━━━━━━━━━ What’s really happening: ❌ New function created on every render ❌ Child components re-render unnecessarily ❌ Memoization breaks silently ❌ Performance issues appear “randomly” ━━━━━━━━━━━━━━━━━━━━━━━ The optimized approach: const Component = () => { const handleClick = useCallback(() => { console.log("clicked"); }, []); return <Button onClick={handleClick} />; }; ✅ Stable references ✅ Predictable renders ✅ Works with React.memo ✅ Scales better in complex UIs ━━━━━━━━━━━━━━━━━━━━━━━ The real takeaway: This isn’t about using useCallback everywhere. It’s about: • Knowing how React compares props • Understanding reference equality • Optimizing when components grow Premature optimization is bad. Blind optimization is worse. ━━━━━━━━━━━━━━━━━━━━━━━ 💬 Honest question: Do you actively watch re-renders in your React apps or only care when users complain?
