Controlling State in React

When I first started learning React, I thought writing more code meant building better features. Turns out… the opposite is often true. One small thing that changed the way I write components: Break large components into smaller reusable ones. Instead of this: function Dashboard() { return ( <div> <Header /> <Sidebar /> <UserStats /> <RecentActivities /> <Notifications /> </div> ) } Think in reusable pieces: StatsCard ActivityItem NotificationItem This makes your code: ✅ Easier to maintain ✅ Easier to reuse ✅ Easier for teammates to understand Clean code isn’t about writing more code. It’s about writing code that future-you will thank you for.

Frontend Learning — Don’t Mutate State Directly As frontend developers, we sometimes update state directly… especially with objects or arrays. It might seem to work, but it can break your UI in unexpected ways. Why this is a problem: -> React may not detect changes -> UI might not re-render -> Leads to unpredictable bugs -> Breaks immutability principles 💡 Key Takeaway: Always create a new copy of state instead of mutating it. ⚡ Common Mistake: Directly modifying state ✅ Better Approach: Use immutable updates #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #CleanCode #BestPractices #CodingTips #LearnInPublic #DeveloperJourney

⚛️ Sharing My React.js Notes Just shared my React.js notes to help anyone who is starting or revising React. React can feel overwhelming at first, but once you understand components, props, state, and hooks, everything starts making sense. I created these notes to simplify the core concepts and make learning React easier for beginners and developers who want quick revision. 📘 These notes focus on: • Components & JSX • Props & State • React Hooks • Event Handling • Basic React Concepts Hope this helps developers who are on their React learning journey 🚀 📌 Save this post for revision 💬 Comment “REACT” if you want the notes 🔁 Share with someone learning React All credit goes to the original creator of the material. #React #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Coding #Developers #TechLearning

Mastering React Hooks is a game-changer for building scalable and efficient applications. ⚛️ From managing simple state to handling complex logic, React Hooks make functional components more powerful and maintainable. 🔹 useState — Manage component state 🔹 useEffect — Handle side effects like API calls 🔹 useContext — Share global data across components 🔹 useRef — Access DOM elements without re-render 🔹 useReducer — Manage complex state logic 🔹 useMemo & useCallback — Optimize performance 🔹 Custom Hooks — Reuse logic efficiently Understanding when and why to use each Hook helps in writing cleaner, reusable, and production-ready React code. 📌 Save this post for quick revision 📌 Share with fellow developers 📌 Keep learning, keep building #React #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #FullStackDeveloper #MERNStack #SoftwareDeveloper #CodingLife #LearnToCode #TechCareer #ReactHooks #DeveloperCommunity #100DaysOfCode #Programming

🚀 Exploring Bun.js – The Fast All-in-One JavaScript Runtime Recently I started experimenting with Bun.js, and honestly it feels like a huge step forward for the JavaScript ecosystem. Instead of using multiple tools like npm, jest, webpack, and node separately, Bun.js combines everything into one runtime. ⚡ Super fast runtime 📦 Built-in package manager 🧪 Native test runner 🔧 Bundler included 🌐 Node.js compatible APIs Quick example: bun create next-app myapp bun install bun run dev Simple. Fast. Powerful. if you want to explore it: 👉 https://bun.com/ As developers, tools that improve performance and developer experience can make a huge difference in how we build modern applications.

🚀 30 Days — 30 Coding Mistakes Beginners Make Day 15/30 I changed the state… but the input field didn’t update 😐 <input defaultValue={name} /> `defaultValue` only sets the initial value. After that, the DOM controls the input — not React. So even when state changed, UI didn’t. Fix 👇 <input value={name} onChange={e => setName(e.target.value)} /> Now React state controls the input. In React: Uncontrolled input → unpredictable Controlled input → reliable Day 16 tomorrow 👀 #30DaysOfCode #reactjs #javascript #frontend #webdevelopment #codeinuse

🚀 React.js Basics: Understanding Props vs State While learning and building projects in React.js, one of the most important concepts to understand is the difference between Props and State. 🔹 State Managed inside the component Can change over time Used for dynamic data like counters, forms, UI updates 🔹 Props Passed from parent to child components Read-only (cannot be modified by the child) Used to share data between components 💡 Simple way to remember: State = Internal data of a component Props = Data passed from parent component Understanding these two concepts clearly helps in building clean, reusable, and scalable React components. I created this visual to make the concept easier for beginners who are learning React UI Development. 🌐 Explore my work: https://allconverthub.com https://lnkd.in/g4Hnzt9Z #ReactJS #FrontendDevelopment #UIDeveloper #JavaScript #WebDevelopment #ReactLearning #FrontendEngineer #Coding

Most React developers know both hooks. But a lot of people still use the wrong one in real projects. useCallback and useMemo look similar… but they solve different problems. Here’s the simple rule: → useCallback = memoize functions → useMemo = memoize values Sounds basic? Still one of the easiest ways to create unnecessary complexity in a React codebase 😅 I’ve seen people: - wrap everything in useCallback - use useMemo where it adds zero value - optimize too early instead of fixing actual re-render issues The truth: These hooks are useful. But only when you understand what exactly you’re stabilizing. Which one do you see misused more often in real codebases? 👇 #React #JavaScript #WebDevelopment #Frontend #SoftwareEngineering #ReactJS #CodingTips #Developers #AITechDaily

I wasted 3 months watching React tutorials. Rewatching. Taking notes. Feeling "ready." Then I opened VS Code and went completely blank. Sound familiar? Here's the thing nobody tells you — tutorials teach you to follow, not to build. And there's a massive difference between the two. So I made this instead. 5 core React concepts. Zero fluff. One slide each. → Components → Props → useState → useEffect → Rendering Lists That's literally 80% of what you need to start building real projects. Save this. Open your editor. Break something. That's how you actually learn React. 🔖 Save this post before you forget ♻️ Repost if this would help someone in your network #React #ReactJS #WebDevelopment #Frontend #JavaScript #LearnToCode #100DaysOfCode #Developer #Coding #wasaydevops
