🚀 Just built a Notes App using React! A simple yet powerful app to create, manage, and organize notes efficiently. This project helped me strengthen my frontend skills and understand real-world component structuring. 🔗 Check it out here: https://lnkd.in/gb38XjAK Would love your feedback and suggestions! 💬 #ReactJS #WebDevelopment #FrontendDevelopment #JavaScript #Coding #Projects #DeveloperJourney

I almost shipped a slow React app. Not broken. Not buggy. Just… slow. Everything worked. But something felt off — clicks felt delayed, UI had that subtle lag that users notice even if they can't explain it. I opened React DevTools Profiler and what I saw genuinely surprised me. One small interaction was triggering re-renders across components that had absolutely nothing to do with it. Functions being recreated on every render. Child components updating for no reason. I wasn't writing bad code. I just didn't understand what React was actually doing under the hood. Three things that changed everything for me: React.memo — child components stopped re-rendering unless their props actually changed useCallback — function references stayed stable between renders instead of being recreated every time useMemo — expensive calculations stopped running on every single render The difference was immediate. The app felt alive in a way it didn't before. No library. No major refactor. Just understanding how React works and using the tools it already gives you. If your React app feels sluggish and you haven't opened the Profiler yet — that's your next 30 minutes sorted. #ReactJS #Frontend #JavaScript #WebDevelopment #Programming

Most React Apps Become Slow… Not Because of React But Because of How We Write Code While learning and building projects, I noticed this Everything works fine in the beginning… But as the app grows — it starts lagging, re-rendering, and becoming messy. The reason? Poor optimization habits. Here are a few simple things I’m focusing on now ⚡ Avoid unnecessary re-renders ⚡ Use useMemo & useCallback when needed ⚡ Keep components small & focused ⚡ Don’t lift state unnecessarily ⚡ Use proper keys in lists What I’ve learned: Performance is not an “advanced topic” It starts with basic habits from day one I’m still improving, but being mindful of these small things is already making a difference #ReactJS #FrontendDevelopment #WebPerformance #JavaScript #BeginnerDeveloper #CleanCode #LearningInPublic

React.js for Junior Developers: My Journey When I started learning React, it felt overwhelming — so many concepts, so many tutorials! 😅 Here’s what helped me the most: • Build small components first • Use props & state to make UI interactive • Experiment with Hooks (useState & useEffect) • Debug often with React DevTools The magic happens when all the pieces come together — suddenly, your small components are a real working app! 🚀 If you’re just starting with React: start small, keep building, and embrace mistakes. Every click, every console log, every bug is a step forward. 🔥 Tip: Try making a mini dashboard or to-do list — you’ll learn more building than reading. #ReactJS #JuniorDeveloper #WebDevelopment #CodingJourney #LearningByDoing

🚀 Formik vs React Hook Form – Which one should you choose? As a frontend developer, handling forms efficiently is crucial. Recently, I explored both Formik and React Hook Form, and here’s a quick comparison 👇 🔹 Formik Easy to understand and beginner-friendly Works well with controlled components Great ecosystem and documentation But… can cause more re-renders (performance impact) 🔹 React Hook Form Built for performance (fewer re-renders ⚡) Uses uncontrolled components Smaller bundle size Better for large and complex forms 💡 My Take: Use Formik if you're starting out or want simplicity Use React Hook Form if performance and scalability matter 👉 In modern React apps, I personally prefer React Hook Form for its speed and flexibility. What do you prefer? 🤔 #React #FrontendDevelopment #JavaScript #WebDevelopment #Formik #ReactHookForm

🚀 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

Your React app is slower than it needs to be. Here's how to fix it. Most devs write React the way they learned it — and never revisit it. The result? Unnecessary re-renders, bloated bundles and lists that freeze on scroll. In this carousel I cover 5 patterns I apply to every React project: → useCallback & useMemo — when to use them (and when not to) → Why state lifting is silently killing your render tree → Code splitting: route-level is the highest ROI change you can make → Virtualisation for long lists — 10,000 rows in under 5ms → The performance checklist, in priority order Save this. Your users will notice the difference. If you found this useful, follow me for weekly React & full-stack tips. What's your go-to React performance trick?

🚀 Confused between Props and Context API in React? Let’s simplify it. When I started building React apps, I relied heavily on props to pass data between components. 💡 It works well… until your app grows. 👉 Problem: Passing data through multiple layers (props drilling) becomes messy and hard to maintain. 💡 Solution: Use Context API when needed. Example: const UserContext = React.createContext(); <UserContext.Provider value={user}> </UserContext.Provider> 👉 Now any component can access user without passing props manually. 🔍 Props vs Context API: ✔ Props • Best for simple & direct data passing • Easy to understand • Great for small apps ✔ Context API • Avoids props drilling • Shares global data easily • Better for medium-scale apps ⚠️ But don’t overuse Context! Too much global state can: • Make components harder to reuse • Impact performance if not optimized 🔥 Lesson: Use Props by default. Use Context when props become a problem. What do you prefer — Props, Context API, or Redux? #ReactJS #JavaScript #WebDevelopment #FrontendDevelopment #CodingTips #FullStackDevelopment

🔥 Unpopular opinion: Most React developers don’t actually understand useEffect. I didn’t either… until my app froze in production. 💥 No errors. No warnings. Just a stuck screen. The culprit? 👇 useEffect(() => { fetchData(); }); Looks normal, right? ❌ 💥 This runs on EVERY render → fetch updates state → state triggers render → infinite loop ♾️ And your app? Dead. ✅ Fix: useEffect(() => { fetchData(); }, []) 💡 Lesson: useEffect isn’t “run this code” It’s “run this code when dependencies change” Most bugs aren’t logic issues. They’re misunderstanding how React works. Follow me more Such learning Content and the mistakes that I had made, so that you shouldn't ✍️👨💻 #ReactJS #Frontend #JavaScript #SoftwareEngineering

"React performance: one trick that changed how I code" I used to re-render my entire app on every state change. Here's what I was missing... After years of building React apps, the single biggest performance win I found was understanding when components re-render — and stopping unnecessary ones dead in their tracks. The fix? Splitting state smartly. Keep fast-changing state close to where it's used, not at the top of your tree. 3 things I now do on every project: ✅ Use React.memo for pure components ✅ Move state down — don't lift it higher than needed ✅ Use useCallback/useMemo only when profiling shows it's needed (not by default) The last point is one most devs get wrong. Premature optimization with useMemo can actually slow things down. What's your go-to React performance tip? Drop it below 👇 #ReactJS #WebDevelopment #Frontend #JavaScript #SoftwareEngineering
