React useEffect Misuse: Syncing with External Systems Only

Ever wondered how things actually work behind the scenes in JavaScript? 🤔 This simple concept changed how I think about building apps 👇 👉 A listener is just code that waits… and runs only when something happens. No constant execution. No unnecessary work. Just event → action ⚡ This is not just basic JS — 👉 this is exactly how Chrome works internally 👉 how Browser extensions communicate 👉 how modern apps stay fast and responsive Once you understand listeners, you start thinking in event-driven systems, not just functions. And that’s where real engineering begins 🚀 #javascript #webdevelopment #frontend #softwareengineering #reactjs #chromeextension

🚀 Master React Router in Minutes! Here’s a simple breakdown of everything you need to know: ✅ What is Routing ✅ SPA Concept ✅ Static vs Dynamic Routes ✅ useParams() ✅ Protected Routes 💡 Key Takeaways: React uses SPA (Single Page Application) Routing helps display components based on URL Dynamic routes make apps scalable Protected routes secure your app 📌 If you're learning React, this is a must-know concept!

Today I explored some core concepts of React that changed the way I see frontend development : • How React works behind the scenes • Rendering process in React • Virtual DOM vs Real DOM • Diff Algorithm (how react updates efficiently) • Client Side Rendering (CSR) • Server Side Rendering (SSR) One thing I found really interesting is how React uses the virtual DOM and diff algorithm to update only the necessary parts of the UI, making apps faster and more efficient. I'm excited to dive deeper and build more projects using these concepts! #React #Javascript #MernStackDevelopment

Today I explored some important concepts in React that make apps more scalable and dynamic. 🔹 Learned Context API to manage global state 🔹 Worked with React Router DOM for navigation 🔹 Implemented routing using RouterProvider and createBrowserRouter 🔹 Built multiple pages: Home, About, Contact 🔹 Learned how to navigate between pages smoothly 🔹 Extracted dynamic parameters (like id) from URL 🔹 Fetched real data from GitHub API (followers) 🔗 GitHub Profile: https://lnkd.in/gMurynAg 📌 Key takeaway: Understanding routing + global state is a big step toward building real-world React applications. #React #WebDevelopment #JavaScript #Frontend #LearningInPublic #100DaysOfCode

Ever clicked two dropdowns and both stayed open at the same time? 😾 Looks unprofessional. Feels broken. Users hate it. Here is how I fixed it in React with just 2 lines : 👉 When Explore opens → force "Degree" dropdown to close onClick={() => {  setIsExploreMenuOpen(!isExploreMenuOpen);  setIsDegreeMenuOpen(false); // ← this one line does it }} 👉 When Degree opens → force "Explore" dropdown to close onClick={() => {  setIsDegreeMenuOpen(!isDegreeMenuOpen);  setIsExploreMenuOpen(false); // ← same idea }} The logic is simple: When you open something → explicitly close everything else. React does not do this automatically. You have to tell it exactly what to close. Small detail. Big difference in user experience. #react #nextjs #javascript #webdevelopment #tailwindcss #buildinpublic #frontenddevelopment

🚀 useEffect vs useLayoutEffect — One Small Difference, Big Impact! As a React developer, I used to think both hooks were almost the same… until I understood when they run 👇 🔹 useEffect Runs after the browser paints the UI 👉 Non-blocking → Better for performance Perfect for: ✅ API calls ✅ Event listeners ✅ Logging 🔹 useLayoutEffect Runs before the browser paints the UI 👉 Blocking → Can affect performance Used for: ✅ DOM measurements ✅ Layout adjustments ✅ Preventing UI flicker ⚡ The Key Difference: Timing 👉 useLayoutEffect runs first 👉 useEffect runs after paint 💡 Golden Rule Always use useEffect unless you specifically need to measure or modify the DOM before it renders. Understanding this small difference can help you avoid performance issues and UI glitches 👀 💬 Have you ever faced flickering issues or layout bugs in React? #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #ReactHooks #LearningInPublic

⏱️ Built a Todo List with Timer using React Tried building a Todo List where each task has its own timer control — small idea but interesting state handling. Features: • Add todos dynamically • Start timer for each task individually • Reset timer per task • Delete tasks • Independent timer state for every item What I learned: • Managing multiple independent states in a list • Handling setInterval / timers safely in React • Avoiding memory leaks with proper cleanup • Structuring components for better state isolation • Updating UI efficiently without affecting other items This was a great exercise in understanding how to handle time-based state and side effects in React.

🚀 Day 7/30 – React Hooks (Game Changer) Today I learned one of the most powerful concepts in React ⚡ 👉 Hooks Today I learned: ✅ Hooks let you use state & lifecycle features in functional components ✅ No need to write class components anymore ✅ Makes code cleaner and easier to manage 💻 Example: import { useState } from "react"; function Counter() { const [count, setCount] = useState(0); return ( <button onClick={() => setCount(count + 1)}> {count} </button> ); } 🔥 Key Takeaway: Hooks = Less code + Better readability + Powerful logic 💡 Bonus: Common Hooks: - useState → manage state - useEffect → side effects - useRef → access DOM Are you using Hooks or still learning them? 👇 #React #Hooks #Frontend #WebDevelopment #JavaScript #CodingJourney

Day 18 — Pos-tI-tUP 📸 A React-based photo posting app where users can upload, edit, and delete posts with images and captions. Tech Stack: • React • Tailwind CSS • react-hook-form Key Concepts Applied: • Lifting state up across components • useRef for programmatic file input • Component composition (Navbar, UploadForm, PostCard) • CRUD operations via state Small project, big learnings. Consistency is the key. 💪 GitHub: https://lnkd.in/gpVakZ8C Live Link: https://lnkd.in/g-edej_E #React #Frontend #WebDev #100DaysOfCode #Day18 #JavaScript

Underrated React libraries more people should be using 👇 1. react-aria → makes accessibility actually manageable 2. valtio → state management without the usual complexity 3. cmdk → build clean command menus (like modern apps) 4. react-resizable-panels → super useful for dashboards 5. usehooks-ts → simple, production-ready hooks Used cmdk recently — really clean and easy to integrate. I’m starting to realize… good frontend isn’t about using popular tools, it’s about using the right ones.
