💡 State vs Props vs Hooks in React JS – Repeated Interview Questions | Day 21 Understanding the difference between State and Props is very important for every React developer. 🔵 State ✔ Manages internal component data ✔ Can change (mutable) ✔ Triggers re-render ⚪ Props ✔ Passed from parent component ✔ Read-only (immutable) ✔ Used for communication 🎯 Interview Tips: State manages data, Props pass data. Mastering this concept makes your React fundamentals strong and helps you crack interviews confidently 🚀 Are you comfortable with State & Props? 👨💻 Follow for daily React, and JavaScript 👉 Arun Dubey #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #Day21

🚀 Did the interviewer ask questions? : What’s the Real Difference? Class vs Functional Component —   Day17 Agar aap React interview ki preparation kar rahe ho, to ye question almost guaranteed hai 👇 👉 Class Component vs Functional Component Earlier, we used Class Components with: • this.state • constructor() • render() method • More boilerplate code But today, developers prefer Functional Components because: • Simple JavaScript functions • useState & other Hooks • No this keyword • Cleaner & shorter code 💡 Best Interview Answer (Short & Smart): Class components use ES6 classes and manage state using this.state and lifecycle methods. Functional components use Hooks like useState and useEffect to manage state and side effects. Modern React applications prefer functional components because they are cleaner, shorter, and easier to maintain. 🔥 Same work. Less code. Better readability. 👨💻 Follow for daily React, and JavaScript 👉Arun Dubey If you're preparing for React interviews, save this post 👇 #ReactJS #FrontendDevelopment #JavaScript #ReactInterview #SoftwareDeveloper 🚀

Mastering the JavaScript Event Loop is key to nailing async code and frontend interviews! 🚀 JavaScript runs on a single thread, so it handles tasks in a smart order: 1. Sync code executes first (call stack) 2. Microtasks next (Promises, queueMicrotask) 3. One macrotask at a time (setTimeout, events) Loop repeats! 🔄 This fixes async bugs, boosts React perf, and crushes interviews! 💡 Drop your answer below! 👇 Who gets it right ? #JavaScript #EventLoop #ReactJS #Frontend #WebDev #CodingTips #InterviewPrep #Programming

🚀 React Interview Topic: Controlled vs Uncontrolled Components When building forms in React, one of the most important concepts is: ✅ Controlled Components vs ⚡ Uncontrolled Components Both work… but they solve problems differently. 🎯 Controlled Component (React State Driven) In a controlled component: Input value is stored in React state React becomes the single source of truth Example: const [value, setValue] = useState(""); <input value={value} onChange={e => setValue(e.target.value)} /> ✅ Best for: ✔ Form validation ✔ Predictable UI behavior ✔ Complex forms ⚡ Uncontrolled Component (DOM Ref Driven) In an uncontrolled component: Input value is managed by the DOM itself React accesses it using useRef Example: const inputRef = useRef(); <input ref={inputRef} /> ✅ Best for: ✔ Quick setup ✔ Simple forms ✔ Less boilerplate code 💡 Key Difference 🔵 Controlled → React controls the input 🟠 Uncontrolled → DOM controls the input 🎥 I explained this topic in detail with examples on my YouTube channel: 🔗 Watch here: (Paste your link) 💬 Which one do you use more in real projects — Controlled or Uncontrolled? #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #ReactDeveloper #CodingInterview #SoftwareEngineering #ReactForms #Programming #TechCommunity #FullStackDeveloper #LearnReact #DeveloperTips
