Prevent Infinite useEffect Loop with Correct Dependencies

In React, you can show or hide components based on conditions 3 ways to do it....  1. 𝗶𝗳/𝗲𝗹𝘀𝗲 if (isLoggedIn) return <Dashboard /> else return <Login /> 2. 𝗧𝗲𝗿𝗻𝗮𝗿𝘆 𝗼𝗽𝗲𝗿𝗮𝘁𝗼𝗿 {isLoggedIn ? <Dashboard /> : <Login />} 3. && 𝗼𝗽𝗲𝗿𝗮𝘁𝗼𝗿 {isLoggedIn && <Dashboard />} Use && when you only want to show something and have nothing to show otherwise. Use ternary operator when you have two options. This is how every login/logout, loading spinner, and error message works in a React app #reactjs #webdevelopment #javascript #MERN

🗂️ Does your app load 10,000 items at once? That's a performance disaster waiting to happen.

Your Next.js app has 3 dead API routes. Most teams miss it. Profile, notifications, settings — 3 routes I deleted last month. Server Actions made them obsolete and most teams haven't noticed yet.

“One small error can crash your entire app… but most devs still code like nothing will go wrong.” Try/Catch isn’t optional. It’s protection. Plan for the error. Not the success. #LaymansLogic #100DaysOfCode #FrontendDev #CodingLife #JavaScript #BuildInPublic

Most React apps render everything immediately, even components users haven’t scrolled to yet. That means unnecessary work for the browser and slower pages. Here is a custom React hook using Intersection Observer that renders components only when they enter the viewport. Perfect for: • lazy-rendering sections • dashboards with heavy widgets • charts and media components • improving scroll performance • reducing initial load cost Small hook. Noticeable performance win. Try it in your next project and you’ll feel the difference. #reactjs #javascript #webperformance #frontenddevelopment #reacthooks #softwaredevelopment #webdev #codingtips #devcommunity #intersectionobserver #performanceoptimization

We often face performance issues when displaying huge lists in React. Apps slowing down, freezing, or lagging on scroll. This happens because React tries to render every item in the DOM at once which quickly becomes a bottleneck. Pagination or infinite scroll can help reduce the initial load but over time, DOM elements still accumulate, making scrolling sluggish. React-virtualized solves this by rendering only visible items, keeping the DOM light and scrolling smooth. For best results, combine it with pagination or infinite scroll. Fetch limited items from the server while virtualized rendering ensures performance, even with thousands of items. #React #WebDevelopment #FrontendDevelopment #JavaScript #ReactJS #UXDesign #WebApp #SoftwareEngineering #TechSolutions #MERNStack #UIUX #BusinessApps #fullstack #WebDevTips #CodeOptimization #FrontendEngineering

Most Next.js developers are still using Pages Router in 2026. Here's why that's a mistake. 🧵 When Next.js released the App Router I ignored it for months. "Too complex. Pages Router works fine." Then I built a production app with App Router... And I never went back. The real difference? Pages Router: ❌ No Server Components ❌ Slower data fetching ❌ Being phased out slowly App Router: ✅ Server Components by default ✅ Fetch data directly in components ✅ Built-in layouts ✅ The future of Next.js If you're starting a new project in 2026 there's only one right answer. App Router. Every time. Are you still on Pages Router? Tell me why 👇 #NextJS #ReactJS #WebDevelopment #FullStackDeveloper #TypeScript #JavaScript #Frontend #100DaysOfCode #BuildInPublic #LahoreTech

🚀 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
