Rethink Overusing useEffect in React

I removed useEffect from my code… and my app got faster ⚡ Yes, seriously. For a long time, I was doing this in React: useEffect(() => { fetchUsers(); }, []); Seemed correct… right? ❌ But in real projects, this caused: • Multiple unnecessary API calls • Data mismatch bugs • Hard-to-control logic 💡 Then I changed my approach: Instead of auto-calling APIs inside useEffect, 👉 I started triggering APIs based on user actions Example: • Search → onChange • Button → onClick ✅ Result: • Better control over API calls • Cleaner component logic • Improved performance (~30% fewer calls) 🔥 What I learned: useEffect is powerful… but overusing it makes your code messy. 💬 Curious: Do you still rely on useEffect for API calls? #ReactJS #FrontendDeveloper #JavaScript #CodingTips #WebDevelopment

🚀 I built a Random Joke Generator Web App… and learned a lot along the way! At first, working with APIs felt confusing 😅 But this project helped me finally understand how things actually work. 💡 What it does: • Generates random jokes using API • Supports multiple categories (Programming, Dark, etc.) • Text-to-speech feature 🔊 • Copy jokes instantly 📋 🧠 What I learned: • API handling (fetch, async/await) • DOM manipulation • Making UI more interactive 🔗 Live Demo:https://lnkd.in/g8yyVQp6 I’m still improving my frontend skills every day. 👉 Which feature should I add next? #WebDevelopment #Frontend #JavaScript #100DaysOfCode

I Finally Understood useEffect… Somehow A few days deeper into React, and things are starting to click, not perfectly, but enough to feel real progress. At first, hooks felt confusing. Especially useEffect. Why does it run? When does it run? Why does it run again? It didn’t make sense… until I stopped overthinking it and started building. Here’s what I’ve worked on so far: -> useState Understanding how state drives UI changes made everything feel more dynamic and controlled. -> useEffect Still not “mastered”, but now I understand how it handles side effects, especially API calls and controlled execution. -> Built small apps Counter app (state updates, re-rendering) Meme generator (API hit using useEffect, dynamic content, event handling) These small builds did more than tutorials ever could, they forced me to connect the dots. The biggest shift? I have stopped trying to memorize React… and started trying to think in React. Still early, but now it feels like direction instead of confusion. Next: Better structure, deeper hooks, and more real-world projects. For developers: How do you clearly decide when to use useEffect, and when not to? #ReactJS #FullStackDeveloper #WebDevelopment #BuildInPublic #JavaScript #LearningJourney

I built a dynamic quiz application using Next.js, TypeScript, and Redux Toolkit to manage state and persistence. The app features two main interfaces: an admin portal where users can add, review, and delete quiz questions with multiple-choice options, and a student page for taking the quiz with real-time scoring and progress tracking. Styled with CSS for a clean, responsive design, it demonstrates full-stack frontend skills in React ecosystem, including form handling, state management, and user experience optimization. Perfect for educational tools or interactive assessments! 🚀 #NextJS #TypeScript #Redux #WebDevelopment #React

Today everything started to feel… more real. React Masterclass (Day 5). I began with: • Sharing state between components • Passing functions as props • Understanding how React handles state updates But instead of stopping there, I asked: How would this actually work in a real app? 💰 So I built a Budget Tracker: • Set initial balance • Add expenses that reduce it in real-time • Dynamic UI based on current state • Data persisted using localStorage • Clean updates using functional state 💡 Key concepts that clicked: • Lazy initialization (run logic only once) • Functional updates (state based on previous state) • Derived values (calculating remaining balance) Small concepts → Real product thinking. #React #Frontend #WebDevelopment #LearningInPublic #JavaScript

🚀 Just built an Advice Generator App using React ⚛️ 💡 Click. Fetch. Learn. Repeat. Every tap brings a fresh piece of real-time advice from an API 🌐 🔥 What I explored: ✨ React Hooks (useState) for state handling ⚡ Async/Await for smooth API calls 🔄 Dynamic UI updates with every click 📊 Tracking how many insights I’ve gained 🎯 Simple project, powerful learning — building consistency one mini project at a time 💪 👇 Try the concept: Keep clicking, keep learning! #WebDevelopment 🚀 #ReactJS ⚛️ #FrontendDevelopment 💻 #JavaScript 🔥 #APIs 🌐 #CodingJourney 🧠 #100DaysOfCode 💯 #BuildInPublic 📢 #UIUX ✨

App was losing users before they even saw the product. Not because of bad design. Not because of bad marketing. Because the page took 6 seconds to load. I spent 2 weeks debugging, fixing, and measuring. Here's exactly what I found — and how I fixed it. 👇 (swipe through the carousel) What's the biggest performance issue you've faced?

🚀 Most people think slow apps = slow internet ❌ But today I learned something deeper 👇 A React app is not just “download and show UI” The browser actually does 3 heavy things: 📥 Download JavaScript 🧠 Parse (understand) it ⚙️ Execute (run) it 👉 Even UNUSED code still gets parsed 👉 Some of it even executes 💥 That means: Big bundle = more browser work = slower app So performance is not just about: 👉 reducing size It is about: 👉 reducing unnecessary JavaScript work That’s where things like: ⚡ Code Splitting 💤 Lazy Loading 🌳 Tree Shaking actually matter 💡 Biggest mindset shift: “Don’t send everything. Send only what the user needs right now.” Learning in public 🚀 #frontend #react #webperformance #javascript #softwareengineering

Gamifying React: Building an Idle Clicker 🎮💰 Can you build a high-performance game engine using standard web technologies? I took on the challenge with my latest project: Idle Clicker. While it looks like a fun game, under the hood, it’s a masterclass in state management and performance optimization: 🔹 Dynamic Scaling: Implemented mathematical formulas to handle exponential growth for upgrades and costs. 🔹 Performance First: Managed rapid state updates (clicks + auto-income) without causing UI lag, ensuring a smooth 60fps experience. 🔹 React Logic: Utilized hooks and custom logic to bridge the gap between "web app" and "game engine." This project proves that whether it's a data dashboard or a game, I focus on building responsive, logic-driven systems that keep users engaged. 🔗 Try it here (Warning: Addictive): https://lnkd.in/dVbqD6Aj #ReactJS #GameDev #WebDevelopment #Logic #JavaScript #Frontend #CodingChallenge #InteractiveDesign
