Recently, I had an interview for a React Developer role. Sharing the questions here in case it helps someone preparing for similar roles. Some of the questions they asked: 1. What is Authentication vs Authorization? 2 What is a Virtual DOM? How is a Virtual DOM created? 3. What is Palindrome? A string that reads the same forward and backward Example: madam, level 4. How JWT is used in real projects? 5 What is HOC (Higher Order Component) in React? Overall, the round was focused on practical understanding of React, JavaScript rather than just theory. #React #JavaScript #Redux #Frontend #InterviewExperience

Understanding ReactJS Folder Structure — Made Simple ⚛️ This visual highlights the most commonly used folders and files in a standard React project — from assets and reusable components to custom hooks, Redux logic, and the application entry point (main.jsx). A well-structured React codebase improves readability, scalability, and team collaboration, and plays a crucial role in building maintainable, production-ready applications. 📌 Save this for reference and share it with fellow developers. #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactDeveloper #MERNStack #SoftwareEngineering #DeveloperCommunity #TechCareers

Most React developers don’t misuse hooks… They just use them without clarity. useState re-renders. useRef doesn’t. That single difference can impact: ⚡ Performance 🧠 Code clarity 🔁 Component behavior Stop choosing hooks by habit. Start choosing them by purpose. Clean React isn’t about writing more code. It’s about making smarter decisions. Which one do you use more useState or useRef? 👇 For more information contact : https://lnkd.in/gNan5xMQ #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactDeveloper #SoftwareEngineering #CleanCode #PerformanceOptimization #TechContent #100DaysOfCode #LearnToCode #ProgrammingTips #FullStackDeveloper #CodingLife #Developers #CrystalZenTechnology

🚀 Confused between Vue, React, and Angular? Here’s a beginner-friendly comparison to help you choose the right frontend framework based on learning curve, scalability, and job demand. Which one are you learning right now? 👇 #WebDevelopment #Frontend #React #Vue #Angular #JavaScript

📌 Improve 1% daily → Become a 10x React developer over time. 💡 Final Thought ------------------------------------------ Clean React code isn’t about writing more code It’s about writing clear code. If you can’t explain it simply, it’s probably too complex. . . ❌ Bad React Code const C = ({ d }) => <p>{d}</p>; --------------------------------- ✅ Clean React Code const Greeting = ({ message }) => {   return <p>{message}</p>; }; ✔ Clear component name ✔ Meaningful prop ✔ Easy to explain to anyone #ReactJS #FrontendDevelopment #JavaScript #CleanCode

Vue vs React vs Angular This comparison makes one thing clear: There’s no “best” framework — only the right one for your goal. If you want a smooth learning path (Vue) If your goal is fast market entry (React) If you’re building large, long-term systems (Angular) #WebDevelopment #FrontendDevelopment #JavaScript #ReactJS #VueJS #Angular

React and Vue solve many of the same problems, but they encourage different ways of thinking. React leans into explicit state flow and composition, which scales well as applications and teams grow. Vue focuses on approachability and clear separation between template, logic, and state, making complex UIs easier to reason about early on. Understanding both isn’t about choosing sides — it’s about choosing the right trade-offs for the system you’re building. #ReactJS #VueJS #FrontendEngineering #JavaScript #WebArchitecture #SoftwareEngineering

JavaScript: the power strip of the web ⚡ One language. Multiple frameworks. Infinite adapters. React. Angular. Vue. Next.js. React Native. ypeScript. Everything plugged into the same outlet… And somehow, it still works 😄 This image perfectly sums up modern frontend development: Not about choosing one tool, But knowing how everything connects. JavaScript isn’t just a language anymore. It’s an ecosystem. A lifestyle. A test of patience. And yes… Unplug one thing and something random stops working. If you’re a frontend developer, you felt this image instantly. Which plug are you using the most right now? 👇 #JavaScript #FrontendDevelopment #React #Angular #Vue #TypeScript #WebDev #TechHumor
