Just built a smoky fluid effect 🔥 This is the kind of effect you usually see on highend, award-winning websites and I broke it down step by step in a YouTube tutorial. From layout → 3D setup → fluid distortion, everything is covered in a simple way. 🎥 Watch the full tutorial: https://lnkd.in/gnEc3U3i #webgl #threejs #reactthreefiber #frontend #webdev #javascript #3danimation #creativecoding

Server-Side Rendering or Client-Side Rendering One of the most impactful decisions in a React project isn't which library to use — it's when to render. After working with Next.js on several production systems, here's a practical breakdown: ✅ Use Server-Side Rendering (SSR) when: • SEO matters (landing pages, public content) • The page depends on frequently updated data • You need faster Time to First Byte (TTFB) ✅ Use (CSR) when: • The page is behind authentication • Interactivity is the core experience • Data doesn't need to be indexed 💡  Use React Server Components when: • You want zero JS sent to the client for static parts • You're fetching data at the component level without prop drilling 📈 The real skill isn't mastering one approach — it's knowing which one fits the problem. What rendering strategy do you default to and why? Drop it in the comments. 👇 #React #NextJS #WebDevelopment #Frontend #JavaScript

🚀 Diving Deeper into JavaScript Events The Event Object is more than just a set of properties—it’s the key to understanding how users interact with web applications. From tracking where a click happens to detecting key combinations, it gives us powerful insights into user behavior. 💡 The deeper we understand events, the better we can: • Build interactive interfaces • Improve user experience • Write smarter, more efficient code Still learning and exploring more every day. #JavaScript #WebDevelopment #Frontend #LearningInPublic #CodeEveryday

useEffect is probably the most powerful - and most misused - hook in React. 🎯 Arun explained it really well, sharing this because I've made  these exact mistakes in real projects: → Forgetting the cleanup function - memory leaks in production 😅 → Wrong dependency array - stale data showing up in dashboards → Fetching data inside useEffect - unnecessary re-renders and   race conditions What changed for me: ✅ Always write cleanup for subscriptions and event listeners ✅ Use React Query for data fetching — avoids most useEffect complexity ✅ Think twice before adding objects/arrays as dependencies 2.5 years of React and useEffect still teaches me something new.

Most websites feel static. Scroll… nothing happens. No feedback. No motion. No life. So developers try to fix it: ❌ Add one library for scroll ❌ Another for parallax ❌ Another for counters ❌ Another for text effects Now the site is heavy and messy. There should be a simpler way. ✅ One setup ✅ Multiple effects ✅ Lightweight ✅ Easy to use That’s exactly what I built 👇 👉 MotionFlow.dev Turn static websites into smooth experiences — without complexity. #motionflow #webdev #frontend #buildinpublic #javascript

Built a Task Pop-up feature using JavaScript to enhance user interaction and improve task management. This helped me understand dynamic DOM manipulation and event handling in real-world scenarios.

🚀 Website Performance Series – Part 5 Many developers focus only on images… but ignore JavaScript impact. Heavy or blocking JS can: • Delay interaction • Increase load time • Hurt user experience ✔ Always audit scripts: • Remove unused • Defer non-critical • Limit third-party usage #JavaScript #Frontend

Watch My Calculator Project in Action! I recently built this calculator using HTML, CSS, and JavaScript, and here’s a quick demo of how it works What I worked on: • Implementing JavaScript logic for calculations • Handling user input and button events • DOM manipulation for dynamic updates • Creating a clean and responsive UI 💡 This project helped me strengthen my understanding of how frontend logic works behind the scenes. Every small project is a step forward, and I’m excited to keep building and improving my skills. 💬 I’d love to hear your feedback! #WebDevelopment #JavaScript #Frontend #Projects #LearningJourney #BSCS

✨ 𝗗𝗮𝘆 𝟳 𝗼𝗳 𝗠𝘆 𝗥𝗲𝗮𝗰𝘁 𝗝𝗼𝘂𝗿𝗻𝗲𝘆 ⚛️🚀 Today I learned about the `𝘂𝘀𝗲𝗥𝗲𝗳` 𝗵𝗼𝗼𝗸, and it felt a bit different from other hooks. Unlike state, updating a ref doesn’t trigger a re-render. That makes it useful for storing values that need to persist between renders without affecting the UI. I also learned how `useRef` can directly access DOM elements, which is helpful for things like focusing inputs, managing scroll, or interacting with elements when needed. What stood out to me is how React gives controlled ways to interact with the DOM without breaking its flow. #ReactJS #JavaScript #WebDevelopment #LearningJourney #FrontendDevelopment
