React Custom Hooks Simplify Code Organization

Day 84 / 365 👨💻 Revisited key concepts around React state management. 🧠 Understanding how useState drives UI updates ⚙️ Breaking down re-render behavior ⏳ Handling async nature of state updates 🧩 Working with multiple states (arrays/objects) ⚠️ Applying Rules of Hooks correctly #365DaysOfCode #React #JavaScript #Frontend

⚛️🚀Building reusable components is one of the best ways to write cleaner, scalable React code. In my latest blog, I break down how I created a dynamic, beginner‑friendly button component that adapts based on props—no more repeating the same markup. From conditional rendering to flexible class handling, this approach keeps your UI consistent and efficient. A great starting point for anyone improving their React workflow! https://lnkd.in/djJWMbZj #ReactJS #WebDevelopment #FrontendDev #ReusableComponents #JavaScript #CleanCode #ReactTips #TailwindCSS #CodingJourney #SoftwareEngineering

Frontend development feels simple… until it doesn’t. At first, it’s just DOM updates and event handlers. But as the application grows: – state spreads everywhere – UI becomes harder to reason about – small changes break unrelated parts And suddenly, complexity takes over. Scalability in frontend is not about performance first. It’s about structure. This is part of a series where I break down how modern JavaScript frameworks are designed and built to handle scale. 👉 Full article in the comments #frontend #javascript #softwarearchitecture

⚡ Lazy Loading in React — a quick visual breakdown → Before: 3.7 MB loaded on page open   → After: 405 KB loaded on page open   → Result: 4.3× faster First Contentful Paint 🚀  All of this with just 2 lines of code using React.lazy() + Suspense. This is a small but often underestimated concept that can significantly improve performance.

just published part 2 of my React internals series , this one covers what actually happens when you call setState and how does re-rendering works. part 1 (initial render): https://lnkd.in/dycpqavw part 2 (re-render): https://lnkd.in/d4tWTwmk #react #javascript #frontend #webdev

I just deleted 30 lines of code from a React component. no refactor. no library. just one hook in React 19. it's called use() — and it changes how you handle async data and context in your components. most devs haven't heard of it yet. swipe through ↓ broke it down simply what's the most boilerplate you've deleted in a single React upgrade? 👇 #react #react19 #javascript #webdev #frontend

Notifications that Demand Attention. 🔥 Just published toast-anchor to npm a zero-clutter, highly structured notification and modal library for JS developers. If you care about precision in your UI, give it a spin. It handles standard toasts, anchor-based confirmations, and full modals right out of the box. 📦 npm i toast-anchor Play around with it here: https://lnkd.in/gq8SCeFX Let me know what you build with it! 🛠️ #webdev #javascript #opensource #npm #frontend

🚀 I used to think lazy loading reduces bundle size ❌ But today I realized something important 👇 Lazy loading doesn’t actually remove your code. Your total JavaScript size mostly remains the same. 👉 What it really does: It splits your code into smaller chunks So instead of loading everything at once, the browser loads only what is needed at the start ⚡ 💡 That means: Performance improves not because code disappears, but because the browser does less work initially This changed how I think about performance: 👉 It’s not just about reducing size 👉 It’s about reducing initial load Learning in public 🚀 #frontend #react #webperformance #javascript

REACT NOTES — PART 5 (Custom Hooks) As applications grow, repeating the same logic across components quickly becomes hard to manage. Custom hooks help by extracting logic into reusable functions, keeping components focused on UI. This post covers: • What custom hooks are and why they exist • Reusing logic without duplicating code • Practical examples like data fetching • Rules of hooks and composition • When to use (and when not to use) custom hooks Good React code is not just about components — it’s about structuring logic cleanly. 📌 Save this if you're working on scalable React applications. #React #FrontendDeveloper #WebDevelopment #JavaScript #InterviewPrep #LearningInPublic #ReactJS #Consistency

🚀 💡 JavaScript Tricky Question Explanation const arr = [4, 10, 2, 8]; const result = arr.find(num => num > 5) + arr.findIndex(num => num > 5); console.log(result); 👉 Output: 11 👉 Explanation: * find() returns the first value > 5 → `10` * findIndex() returns its index → `1` * Final result → `10 + 1 = 11` ⚡ Both stop at the **first match** #JavaScript #WebDevelopment #Frontend #CodingInterview #JSConcepts
