⚛️ React Machine Coding Round — Part 1: Pagination Component 🚀 I recently started practicing machine coding round problems in React, and here’s my first one — a fully functional Pagination Component 🔥 📦 Tech Stack: React.js | Axios | CSS 🧩 Key Features: ✨ Fetched product data from an API (dummyjson.com/products) ✨ Implemented dynamic pagination logic ✨ Added Prev/Next navigation with active page highlighting ✨ Built a responsive and clean UI using pure CSS 💡 This project helped me strengthen my understanding of state management, array slicing, and pagination logic in React. 💬 I’d love to hear your thoughts — what improvements or extra features could be added that are often asked in React machine-coding interviews? It’ll help me refine this project further as I continue practicing! 🚀 💻 GitHub Repository: 👉 https://lnkd.in/gXXCYQqq #ReactJS #FrontendDevelopment #JavaScript #ReactDeveloper #WebDevelopment #MachineCoding #CodingChallenge #SoftwareEngineering #FrontendEngineer #LearnReact

💻 React.js Coding Challenges I’ve Been Practicing 🔥 After exploring React interview theory questions last week, I shifted gears this week — diving into hands-on coding challenges that really test your problem-solving skills 🚀 Here are some fun and practical ones I’ve been tackling 👇 ⚛️ Hooks & Logic 1️⃣ Build a custom hook for fetching data with loading and error states 2️⃣ Implement a debounce hook to control rapid API calls (like search inputs) 3️⃣ Create a usePrevious hook that tracks the previous value of a prop or state ⚙️ Performance Optimization 4️⃣ Implement lazy loading for components using React.lazy + Suspense 5️⃣ Use React.memo, useCallback, and useMemo to prevent unnecessary re-renders 6️⃣ Optimize large list rendering using react-window or virtualization 🧩 State Management 7️⃣ Build a mini Context + Reducer setup (without Redux) 8️⃣ Sync state with localStorage using a custom hook 🧪 Testing Challenge 9️⃣ Write a test for a component that fetches data using Jest + React Testing Library 🔟 Mock API calls and assert correct rendering for loading, success, and error states 💡 Key takeaway: “The best way to prepare for interviews is to build small, real things repeatedly. Theory makes sense only when you see it in action.” Would you like me to share step-by-step explanations or more challenges next week? 💻 Comment “🔥 Challenge Accepted” if you’re up for it! #ReactJS #FrontendDeveloper #ReactHooks #JavaScript #WebDevelopment #CodingChallenge #InterviewPreparation #CareerGrowth

💻✨ Building Every Logic By Yourself Is the Real Skill! Today I coded a small React feature — delete & filter employee data using simple useState() and filter() logic. And you know what I realized? 👉 Writing logic on your own (without copy-pasting) is the best way to grow as a developer. 🚀 In today’s job market — and especially after 2025 — only those who can think, debug, and create their own logic will stand out. So never stop coding. Even if it’s a repeat task, do it again, do it better — that’s how mastery happens. 💪 Stay consistent, stay logical, and keep building — line by line, thought by thought. #ReactJS #FrontendDevelopment #JavaScript #LearningByDoing #ConsistencyIsKey #WebDevelopment #CareerGrowth #UIMagic #KeepCoding #DevelopersJourney #ReactDeveloper #CodeNewbie

🚀 Hello everyone, after facing so many React.js interviews one idea comes in my mind that's I've to collect all those challenges & make a single project. So I built a complete website with 20+ practical challenges that are actually asked in real interviews. ✨ What's Inside: - Data tables with sorting, search & pagination - Infinite scroll using Intersection Observer API - Drag-and-drop Kanban boards - Multi-step forms with validation - Auto-complete with debouncing - Custom hooks (useDebounce, usePrevious) - Real-time chat UI - Image galleries with lazy loading ...and 12 more challenges! 💡 Why I Built This: Stop memorizing tutorials. Start building real components that interviewers ask for. Every challenge includes: ✅ Complete working code ✅ Best practices ✅ Modern React patterns ✅ Responsive design 🔗 Live Demo: [https://lnkd.in/dMSFQ7db] 💻 GitHub: [https://lnkd.in/dBtCbFdF] This project is 100% free and open source. Perfect for developers with 0-4 years of experience preparing for React interviews. #React #JavaScript #WebDevelopment #OpenSource #InterviewPrep #ReactJS #Frontend #Coding #Developer #WebDev #Programming

💡 React Expert, but Interview Focused on OOP — Here’s What Happened 👇 A friend of mine (a strong React developer 💪) recently attended a front-end interview. He expected deep questions on React Hooks, state management, and performance optimization… But instead — the interviewer asked about Object-Oriented Programming concepts! 🤔 He was surprised — “OOP in React? Isn’t React functional?” But then he realized something interesting 👇 Even in modern React (with function components & hooks), OOP ideas are still very relevant: 🧩 Encapsulation → Custom hooks like useCounter() hide internal logic. 🎯 Abstraction → Hooks such as useFetch() simplify complex logic. 🎭 Polymorphism → Same interface, different behavior — <Button variant="primary" /> vs <Button variant="danger" />. 🏗️ Inheritance (via Composition) → Reusing layout/UI like <Card><ProductInfo /></Card>. He explained these concepts with React examples — and impressed the panel instantly. 💥 It was a great reminder that: “Even though React is functional, the mindset of OOP still makes your code clean, modular, and reusable.” Whether you’re a React dev or a JS enthusiast — never skip the fundamentals. They always find their way into the interview. 😄 #ReactJS #OOP #Frontend #WebDevelopment #JavaScript #InterviewExperience #Learning

🚀 JavaScript Interview Challenge: Can you guess the output? Let’s test your understanding of Event Loop, Microtasks and Async/Await 👇 Code snippet -> console.log('1'); setTimeout(() => {  console.log('2'); }, 0); Promise.resolve().then(() => {  console.log('3'); }); (async function() {  console.log('4');  await Promise.resolve();  console.log('5'); })(); console.log('6'); Before scrolling down, take 10 seconds and think - What do you think will be printed in the console (and in what order)? Drop your answer in the comments 👇 ⚙️ Let’s understand step-by-step: 1️⃣ console.log('1') → runs immediately (synchronous) 2️⃣ setTimeout(...) → goes to the macro task queue 3️⃣ Promise.resolve().then(...) → goes to the microtask queue 4️⃣ Inside the async IIFE: 🔹console.log('4') → runs immediately 🔹await Promise.resolve() → pauses here; the continuation (console.log('5')) goes to microtask queue 5️⃣ console.log('6') → runs next (still in sync phase) Now, the synchronous part is done. Next, the microtasks (Promises, async/await continuations) run: ➡️ '3' ➡️ '5' Finally, macro task (from setTimeout) runs: ➡️ '2' 💬 Comment below 👇 Did you get this right on your first try? Or were you surprised by where '3' and '5' appeared?
