Mastering JavaScript DOM Manipulation is a game-changer for every developer 🚀 From selecting elements to handling events and dynamically creating UI —these are the core skills that bring your web apps to life. ✨ Key takeaways: • Target elements efficiently • Update content & styles dynamically • Handle user interactions smoothly • Build and remove elements on the fly Start applying these concepts in your projects and level up your frontend skills 💻🔥 #JavaScript #WebDevelopment #Frontend #Coding #LearnToCode #DeveloperLife #Programming #TechoSkills #DOM #JavaScriptTips

I built a Pomodoro timer into ACE and honestly it's been one of those features I didn't know I needed until I had it. The idea was simple. I was using ACE to study and kept switching tabs to find a timer. So I just built one in. 25 minutes. Focus. Break. Repeat. If you're building something, don't sleep on the small features. Sometimes the thing that makes your product actually usable isn't the AI or the fancy architecture. It's the 25 minute timer sitting quietly in the corner. #buildinpublic #nextjs #webdevelopment #javascript #frontenddevelopment

Just built a simple but satisfying color loop using JavaScript — every click transitions the background through a smooth sequence of vibrant colors. It’s a small interaction, but it shows how powerful DOM manipulation + a bit of creativity can be. 💡 What’s inside: – Color arrays + looping logic – Smooth CSS transitions – Interactive UI feedback Sometimes it’s the little details that make a project feel alive. #JavaScript #WebDevelopment #Frontend #Coding #UIUX #100DaysOfCode #LearnToCode

Excited to share my latest project: a modern, responsive calculator built using HTML, CSS, and JavaScript! It’s fully functional, works on desktop and mobile, and is styled with a clean, modern UI.

Most frontend developers are still writing raw Intersection Observer code by hand. It works but it adds boilerplate, cleanup logic, and SSR concerns that distract from the actual problem. There is a React hook that handles all of this quietly in the background: useInView from react-intersection-observer. It is one of the most practical hooks in the React ecosystem and, in my experience, one of the least talked about. WHAT IT SOLVES Lazy loading images and components only when they enter the viewport Triggering scroll-based animations without fighting useEffect and useRef Firing analytics events when a section becomes visible Building infinite scroll without a third-party pagination library Auto-playing media only when it is actually in view WHY IT DOES NOT GET ENOUGH ATTENTION Most learning resources teach Intersection Observer from the ground up, which builds understanding but rarely translates into production-ready patterns. This hook is the practical layer on top of that knowledge. It handles unmount cleanup, root margin configuration, SSR-safe behavior, and one-time trigger support things that developers typically spend time rediscovering on their own. The next time a design requirement involves scroll-triggered behavior, reach for this before writing the observer setup manually. What patterns are you using it for? Would be glad to hear how others are applying it. #React #Frontend #WebDevelopment #JavaScript #ReactHooks

Your useEffect is firing 6 times. It's probably not what's in the dependency array. I had [options] in mine. One dependency. Looked fine. The effect ran on every single render anyway — hammering my API with duplicate calls I couldn't explain. The problem wasn't the value. It was the reference. options was an object getting recreated fresh on every render, so React saw a "new" dependency every time — even when the actual data hadn't changed. React doesn't deep-compare objects in the dep array. It checks identity. Fix was wrapping options in useMemo. Two lines. Effect ran once. Done. But honestly, the bigger shift was realising I'd been thinking about dependencies wrong. It's not just what is in the array — it's whether the things in the array are actually stable between renders. If your effect fires more than it should, check the stability of your deps, not just the list. What kills you about useEffect? Curious if this one's common. #react #javascript #reacthooks #frontenddevelopment #webdev

https://lnkd.in/dpPxiwHY — I spent years manually squinting at code changes before I decided to build a better way as a Frontend Engineer. When you’re working with complex TypeScript files, a simple visual check isn't enough to catch those hidden bugs. I built this Diff Checker to handle the heavy lifting that standard text editors sometimes overcomplicate. For the foundation, I went with Next.js 15. The speed is incredible for a tool that needs to be snappy and SEO-friendly. I used TypeScript to ensure every character comparison was type-safe, preventing those annoying crashes during large file comparisons. One of my favorite parts of the build was using Biome. It kept the codebase incredibly clean without the overhead of traditional linting tools. I actually remember a project where I accidentally merged two versions of a config file because I didn't have a quick way to compare them side-by-side. That 2-hour debugging nightmare was the catalyst for adding this to my platform. 😅 The UI is powered by Tailwind CSS to keep it lightweight and responsive across all my 300+ tools. To make sure the diffing logic was bulletproof, I ran extensive end-to-end tests using Playwright. I even leveraged Cursor to help me optimize the diffing algorithm for better performance on massive text blocks. Development was lightning fast thanks to Vite, making the iteration loop almost instant. It’s not just a calculator; it’s about making our daily dev workflow less error-prone and more efficient. 🚀 Do you still rely on your IDE for diffs, or do you prefer a dedicated web tool for a quick check? #DiffChecker #FrontendEngineer #TypeScript #ReactJS #WebDev #NextJS #CodingTools #JavaScript #SoftwareEngineering #TailwindCSS #ViteJS #Programming #CodeReview #WebPerformance #DeveloperExperience

🚀 Frontend Performance — Learning in Public Over the last couple of days, I explored Lighthouse-based performance analysis on a real application. Key learnings 👇 🧠 Main Thread Matters 👉 Browser runs on a single thread 👉 Heavy JS → slower interaction 🚦 Render-Blocking Resources 👉 CSS/JS can delay UI rendering ⛓️ Critical Request Chain 👉 Too many dependencies → slower loading 📊 Lighthouse Insight 👉 It’s not about score 👉 It’s about identifying root causes 🎯 Big takeaway: Performance = reduce work + remove blockers 📌 Next: Building a real-world performance audit report #Frontend #WebPerformance #JavaScript #ReactJS #SoftwareEngineering #LearnInPublic

“Objects & Arrays are basic…” — until you actually build something real. 👀 So instead of just watching tutorials, I challenged myself to turn concepts into a **fully functional Notifications Page** 💻⚡ ✨ What started as simple JavaScript: 👉 Objects → storing notification data 👉 Arrays → managing multiple items 🔥 Turned into: ✔ Real-time UI updates ✔ “Mark all as read” feature ✔ Dynamic unread counter ✔ Clean, responsive design (desktop + mobile) ✔ Interactive hover & focus states This project made one thing clear: 💡 *The difference between knowing JavaScript and using JavaScript is BUILDING.* No frameworks. No shortcuts. Just pure logic + DOM. And honestly… this is where things start getting exciting 🚀 🔗 Live Demo: https://lnkd.in/dTVdciyF 💻 GitHub Repo: https://lnkd.in/dWPdZ-zD #JavaScript #FrontendDevelopment #WebDev #BuildInPublic #CodingJourney #LearnByBuilding #FrontendMentor #100DaysOfCode #Developers #Tech
