Your React app is doing way more work than you think. 🔁 Every time your component re-renders, JavaScript recreates every function and recalculates every value inside it — even if nothing changed. useCallback and useMemo exist to stop that waste. But most developers use them wrong — or not at all. Let's fix that. 👇 #ReactJS #ReactHooks #useCallback #useMemo #ReactPerformance #JavaScript #Frontend #FrontendDevelopment #WebDevelopment #SoftwareEngineering #Programming #100DaysOfCode #DevCommunity #LearningInPublic #SoftwareDevelopment

Most React devs bring their SPA habits into Next.js — and their users pay the price. 👇 You've written it a hundred times: useState for data, useEffect to fetch it, a spinner while they wait. It works in React. In Next.js App Router, it's the wrong pattern entirely. Server Components let you fetch data inside the component — on the server, before the page hits the browser. No loading state. No extra JS bundle. No hydration issues. HTML that arrives ready. I've swapped dozens of useEffect fetch patterns for async Server Components and the Lighthouse scores jump immediately. Use the server for reads. Use useEffect for things only the browser can do. #NextJS #ReactJS #WebDevelopment #JavaScript #TypeScript #AppRouter #ServerComponents #ReactHooks #FrontendDeveloper #SoftwareEngineer #CleanCode #100DaysOfCode #WebPerformance #Programming #WebDev #NextJS14 #FullStackDeveloper #CodeQuality

❤︎ Revising My React Skills ✿ •󠁏✦➤ Project 2: Todo List App (React Practice) ► I already have a basic understanding of React, and I’m currently strengthening my skills by building mini projects through hands-on practice. ► In this project, I worked on improving my React fundamentals by implementing core functionality like state management, form handling, and dynamic UI updates. 💡 What I practiced: . React state management using useState . Form handling and validation . Adding and deleting tasks dynamically . Preventing duplicate entries 🎯 Goal: ► To improve my React skills by building real-world mini projects consistently. 🔗 Code available on GitHub (linked in profile) #ReactJS #JavaScript #FrontendDevelopment #WebDevelopment #CodingJourney #100DaysOfCode #MERNStack #Programming #LearnToCode

🚀 React Series - Day 5 useEffect - Making React Work with the Outside World Not everything in an app is just UI rendering. Sometimes you need to: • Fetch data from APIs • Run logic after rendering • Set up timers or listeners This is where useEffect is used. It runs after a component renders and allows you to handle these “side effects” cleanly. With the dependency array, you can control when it runs: • Empty array → runs once • With values → runs when those values change 👉 It’s a key concept for handling real-world app behavior in React. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

Me: Watches 50 tutorials on React Also me: Still can’t build a simple app 😭 Reality check 👇 You don’t learn development by watching. You learn by BUILDING. Here are 3 frontend projects that will actually make you job-ready: 1️⃣ Portfolio Website (HTML, CSS, JS) → Learn fundamentals + design 2️⃣ API-Based App (React + API) → Learn real-world data handling 3️⃣ Fullstack Project (Frontend + Backend) → Understand how everything connects Stop consuming. Start building.

Most React developers ignore this hook… until their app becomes a mess. I did the same. At first, everything was simple. A few states here and there → useState was enough. But then… More features → more states More logic → more confusion And suddenly, I had no idea what was updating what. That’s when I discovered useReducer. And honestly, it changed how I think about state. Instead of randomly updating values, you start thinking in actions. 👉 “What happened?” 👉 “How should state change?” That’s it. No more messy logic scattered everywhere. Everything becomes predictable. 💡 What I learned: • When state logic starts getting complex → stop using only useState • When multiple actions control the same state → think useReducer • When updates depend on previous state → useReducer is 🔥 The best part? You stop writing confusing code and start writing structured logic If you're learning React seriously, don’t skip this hook like I did. It’s not “advanced”… it’s just misunderstood.

Stop searching for the best language and start mastering JavaScript. One language, endless possibilities. Whether you want to build a mobile app, a 3d game, or a complex server-side system—JavaScript has a library or framework for it. As the image shows, JS isn't just for websites anymore; it’s for everything. Which JS combination are you currently mastering?

Ever wondered what actually happens inside React when your app updates? React does not directly change the browser UI every time something updates. Instead, it creates a Virtual DOM, which is a lightweight copy of the real DOM. When data changes, React builds a new Virtual DOM and compares it with the previous version. This process is known as reconciliation. • React checks what has changed between two versions • It updates only those specific parts in the real DOM • This makes updates faster and avoids unnecessary reloading React also follows a component-based structure. Each component manages its own state and logic, making the code easier to understand, reuse, and maintain. When state or props change, React decides when and how to re-render efficiently. This is why React applications stay fast even when they become large and complex.

Today I learned something simple… but powerful. In React & Vue apps, anything you put inside the public folder gets copied as-is into the final build (dist or build folder). No bundling. No optimization. No magic. At first, I thought everything goes through the build pipeline… but that’s not true 👇 - Files in src → processed, optimized, bundled - Files in public → directly copied #React #Vue #WebDevelopment #JavaScript #Frontend #TIL #Programming

⚛️ useEffect is simple… until it breaks your app 💀 Most React devs think they understand useEffect… But misuse it → and your app turns into a bug factory 😵💫 Here’s what you really need to know 👇 ⚡ useEffect = Side effects handler (API calls, timers, DOM updates) ⚡ No dependency array? Runs on EVERY render → performance killer 🚨 ⚡ Empty dependency array [] Runs only once (on mount) — perfect for API calls 🔥 ⚡ Dependency-based execution Runs when values change → controlled updates 🎯 ⚡ Cleanup function = underrated hero Prevents memory leaks & unwanted behavior 🧹 ❌ Beginner: “useEffect works somehow” ✅ Pro: “I control when & why it runs” 💬 React isn’t hard… Understanding lifecycle is the real game 📌 Save this before your next React project #ReactJS #useEffect #Frontend #WebDevelopment #JavaScript #Coding #Developers #Programming
