🚀 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

🧠 Today I learned something powerful in React: Zustand As I continue building my frontend skills, I explored a lightweight state management library called Zustand — and honestly, it changed the way I think about managing state in React apps. Before this, I mostly used useState and props drilling, which works fine for small apps. But when the app grows, sharing state between components becomes messy and hard to maintain. That’s where Zustand comes in. 🚀 What I learned about Zustand: It allows you to create a global state store outside components Any component can access or update the state directly No need for Context Provider or complex Redux setup Clean, minimal, and very easy to use 💡 Simple idea that helped me understand it: Instead of passing data through components → Zustand keeps the data in one shared store that every component can use directly. This made my code: ✔ Cleaner ✔ More scalable ✔ Easier to manage I really enjoy discovering tools like this because they show me how real-world React applications are structured.

I remember struggling with forms in React… trying different libraries, fixing validation issues, and optimizing performance. ⚛️ That’s when I explored Formik vs React Hook Form. Formik felt simple and quick to start. But as projects grew, I started leaning more towards React Hook Form for better performance and flexibility. Now my go-to depends on the project: • Formik → quick and lightweight setups • React Hook Form → scalable & performance-focused apps There’s no “one perfect choice” - it’s about what fits your use case. Which one do you prefer for your React projects? 👇 #ReactJS #FrontendDevelopment #WebDevelopment #JavaScript #ReactDevelopers

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

🚀 Getting Started with React? Let’s break down the core concepts! Whether you're new to React or revisiting the fundamentals, understanding these building blocks is key to becoming a confident front-end developer. 🧩 Components – The heart of any React app. Think of them as reusable puzzle pieces. ✨ JSX – Write markup-like syntax that gets transformed into JavaScript. Cleaner, simpler, elegant. 📦 Props – Pass data between components just like HTML attributes — but way more powerful! 🧠 State – Manage dynamic data inside a component. Every component can have its own state. ⚡ Events – Handle user interactions with React’s synthetic event system — consistent across all browsers. 🔁 Lifecycle – Tap into component life stages with methods like componentDidMount() and componentDidUpdate(). Master these, and you're well on your way to building dynamic, modern web apps! 👉 Which React concept do you find most challenging or interesting?

❓ How does React improve performance in large-scale applications? 🚀 🚀 Day 25/30 – React Learning Journey Today I learned how React handles performance optimization in real-world apps. Here are key concepts 👇 🔹 Code Splitting Load only required components using dynamic import → Faster loading & better performance 🔹 Lazy Loading React.lazy() loads components when needed 🔹 Memoization Avoid unnecessary re-renders using React.memo() 🔹 Pure Components Only re-render when props/state actually change 🔹 Efficient Reconciliation React updates only changed parts of DOM (Virtual DOM) 💡 Performance matters when your app grows. Small optimizations = big impact 🚀 👉 Question: Which React performance technique have you used in your project? #ReactJS #FrontendDeveloper #JavaScript #WebDevelopment #LearningInPublic #Abhishek841101 🔥

🔥 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

🚀 Leveling up your React performance game! If you're building modern apps with ⚛️ React, understanding these two hooks can seriously boost your app's efficiency: 🔹 useMemo Optimize expensive calculations by memoizing results. It only recomputes when dependencies change — saving performance and avoiding unnecessary work. 💡 Example: const result = useMemo(() => computeExpensiveValue(a, b), [a, b]); 🔹 useCallback Memoize functions to prevent unnecessary re-renders, especially when passing callbacks to child components. 💡 Example: const handleClick = useCallback(() => { // logic here }, [deps]); ✨ Pro Tip: Use them wisely — overusing these hooks can actually hurt performance instead of helping! 📌 When to use: ✔️ Heavy computations → useMemo ✔️ Stable function references → useCallback Keep your apps fast, clean, and scalable 💪 #ReactJS #WebDevelopment #Frontend #JavaScript #Programming #100DaysOfCode

"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

I built a complete enterprise app with NestJS in 48 hours. Here's everything I learned — explained so simply that even a non-developer can understand. NestJS has only 3 concepts: → Module (the container) → Controller (the receptionist) → Service (the worker) That's it. Everything else is this pattern repeated. I made a visual guide breaking down: • Why NestJS exists (and when NOT to use it) • The 3 building blocks with real code • How every request flows — 5 steps • Decorator cheat sheet (save this) • NestJS vs Express — honest comparison Swipe through the carousel ⬇️ --- What backend framework are you using in 2026? ♻️ Repost if this helped someone in your network 💾 Save for later reference #nestjs #backenddevelopment #typescript #webdevelopment #spftwareengineering #development #javascript
