React Pagination for Large Data Sets

🚀 Built a React App Using useReducer ⚛️ I recently built a "React Quiz" app to strengthen my understanding of state management in React. 🧠 Key learnings: Managing complex state with useReducer Handling async data (loading questions from a mock API) Managing loading, error, and ready states ⚡ Answer selection & smooth navigation between questions Tracking progress 📊 Completing & restarting the quiz 🔁 Implementing a countdown timer using useEffect ⏱️ 💡 This project helped me understand when to use useReducer over useState for more structured and scalable state logic. 🔗 GitHub Repo: https://lnkd.in/g8VeyXhi Feedback is welcome 🙌 #React #JavaScript #FrontendDevelopment #WebDevelopment #ReactJS #LearningByBuilding

🚀 Just built a Notes App using React! A simple yet powerful app to create, manage, and organize notes efficiently. This project helped me strengthen my frontend skills and understand real-world component structuring. 🔗 Check it out here: https://lnkd.in/gb38XjAK Would love your feedback and suggestions! 💬 #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #Coding #Projects #DeveloperJourney

⚛️ Why Your React App Re-Renders Too Much (And How Senior Devs Fix It) One of the biggest performance killers in React apps is unnecessary re-renders… and most developers don’t even realize it. 👉 Common mistakes: ❌ Passing new object/array props on every render ❌ Inline functions inside components ❌ Not using memoization properly Example: Every render creates a new function → child re-renders again 💡 Senior-Level Fix: ✔ useCallback → memoize functions ✔ useMemo → memoize expensive calculations ✔ React.memo → prevent unnecessary re-renders But here’s the catch 👇 Don’t overuse them. ⚡ Rule: “Optimize only when there is a real performance issue.” Blind optimization can make your code worse. 👉 Pro Tip: Use React DevTools Profiler to identify actual re-render problems. Performance is not about writing more code… it’s about writing smarter code. #reactjs #frontend #performance #javascript #webdevelopment #fullstack #softwareengineering #optimization

⚡ React Performance Optimization Tip Your React app is slow? This might be the reason 👇 Unnecessary re-renders. Solution → React.memo const Child = React.memo(({data}) => { console.log("render") return {data} }) Now component only re-renders when props change. 💡 Use when: • Large list rendering • Heavy components • Performance issues Small optimization → Big performance gain 🚀 I'm sharing daily React tips while preparing for new opportunities.

Most React devs are still making users wait for the server. 🙄 I was too. Until I found `useOptimistic` in React 19. **What changed:** → UI updates the moment user clicks → No spinner, no waiting, no freeze → If server fails - React auto rolls back to previous state → Zero extra code for error handling This is exactly how Instagram, X, and LinkedIn build their like buttons. The difference between a "good app" and a "feels native" app is this one pattern. `useOptimistic` ships with React 19. No extra install. If you're still on the old pattern - try this today. Drop a 🔥 if this was new to you! What pattern do you use for instant UI feedback? Let me know 👇 #React19 #ReactJS #useOptimistic #Frontend #WebDevelopment #JavaScript #FullStackDeveloper

React is easy to start… But hard to master. At first, it’s just components and props. But then you realize the real game: 👉 State management 👉 Performance optimization 👉 Re-render control A small mistake in structure can slow down your entire app. What I’ve been focusing on: ✔ Writing reusable components ✔ Avoiding unnecessary re-renders ✔ Keeping logic clean and scalable Because good UI isn’t just about looks… It’s about performance + maintainability. #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #UIUX

✨ 𝗗𝗮𝘆 𝟯 𝗼𝗳 𝗠𝘆 𝗥𝗲𝗮𝗰𝘁 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 ⚛️🚀 Today I learned about 𝗥𝗲𝗮𝗰𝘁 𝗛𝗼𝗼𝗸𝘀, especially the 𝘂𝘀𝗲𝗦𝘁𝗮𝘁𝗲 𝗵𝗼𝗼𝗸 — and this finally made React feel more practical. Before this, I was thinking about how we usually update the UI manually in JavaScript — selecting elements, changing text, updating the DOM step by step. It works, but it can get messy and hard to manage as the app grows. With `𝘂𝘀𝗲𝗦𝘁𝗮𝘁𝗲`, React handles that for us. We just update the 𝘀𝘁𝗮𝘁𝗲, and React automatically updates the UI. No need to manually touch the DOM every time. That shift in thinking was really interesting — instead of telling the browser 𝗵𝗼𝘄 to update, we just tell React 𝘄𝗵𝗮𝘁 the state should be.

Day 18 #100DaysOfCode 💻 Today I learned React Routing (React Router). React Router helps create multiple pages in a single-page application (SPA) without reloading the browser. It allows smooth navigation between components like Home, About, and Contact. Key idea: Use BrowserRouter, Routes, and Route to define paths and components. import { BrowserRouter, Routes, Route } from "react-router-dom"; import Home from "./Home"; import About from "./About"; function App() { return ( <BrowserRouter> <Routes> <Route path="/" element={<Home />} /> <Route path="/about" element={<About />} /> </Routes> </BrowserRouter> ); } This makes navigation faster and keeps the app dynamic and user-friendly.
