🚀 Just built a Rock–Paper–Scissors Game with a Clean UI ✊📄✂️ A small project, but a great exercise to strengthen core front-end skills using only HTML, CSS, and JavaScript — no frameworks, no libraries. Features: • Clean and minimal UI • Emoji-based hand buttons • Randomized computer moves • Live score tracking (User vs Computer) • Instant result feedback • Fully responsive design Building small projects like this is one of the best ways to practice DOM manipulation, UI design, and JavaScript logic. Try the game here: https://lnkd.in/d4YMjAZj Would love to hear your feedback! 💻 #webdevelopment #javascript #frontend #html #css #coding

Day 18 - Product Filter & Search 🔍✨ Today, I built a dynamic product filtering system using HTML, CSS, and Vanilla JavaScript! What it does: ✅ Real-time Search: Products update instantly as you type. ✅ Category Filter: Sort items by Electronics, Fashion, or Kitchen. ✅ Combined Logic: The search works inside the selected category for a better user experience. Focusing on DOM manipulation and clean logic today. One step closer to mastering JavaScript! 🚀 #WebDev #JavaScript #Frontend #CodingJourney

Excited to share a recent front-end practice project. I built a straightforward, interactive webpage to solidify my understanding of vanilla JavaScript and DOM manipulation. - Dynamic Styling: Created a button that triggers a color change upon interaction using JavaScript event listeners. - Time-Based Logic: Programmed a dynamic greeting alert that checks the current time (new Date().getHours()) and delivers a context-aware message (Morning, Afternoon, or Evening). - Interactive Calculator: Built a simple calculator that takes values from user input fields, parses the data, performs the addition, and instantly updates the DOM with the correct result. It is always rewarding to see the code come to life on the screen. You can see the HTML, CSS, and JS logic working together in the attached video. #JavaScript #WebDevelopment #FrontEnd #CodingJourney #HTML #CSS #DOMmanipulation #cognifyz #cognifyzTechnologies

𝐖𝐡𝐞𝐧 𝐲𝐨𝐮𝐫 𝐜𝐨𝐝𝐞 𝐥𝐢𝐭𝐞𝐫𝐚𝐥𝐥𝐲 𝐬𝐢𝐠𝐡𝐬 𝐚𝐭 𝐲𝐨𝐮𝐫 𝐦𝐢𝐬𝐭𝐚𝐤𝐞𝐬... 🤦♂️🔊 I just finished a project where I built a 𝐒𝐢𝐦𝐨𝐧 𝐒𝐚𝐲𝐬 𝐁𝐫𝐚𝐢𝐧 𝐠𝐚𝐦𝐞, and I wanted it to feel a bit more "alive." So, instead of the usual boring buzzer, I added a custom “𝗳𝗮𝗮𝗮𝗵” sound that plays every time you lose. 😂 😂 It’s surprisingly motivating (or frustrating, depending on your high score)! This was a great chance to get hands-on with Vanilla JavaScript and manage complex game states. Here’s a breakdown of what I implemented: 🚀 𝐊𝐞𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬:  • 𝐃𝐲𝐧𝐚𝐦𝐢𝐜 𝐋𝐨𝐠𝐢𝐜: Classic “repeat the sequence” setup where the pace picks up as you progress.  • 𝐏𝐞𝐫𝐬𝐢𝐬𝐭𝐞𝐧𝐭 𝐒𝐜𝐨𝐫𝐢𝐧𝐠: Integrated localStorage so your Best Score sticks around between sessions.  • 𝐌𝐨𝐝𝐞𝐫𝐧 𝐓𝐨𝐨𝐥𝐢𝐧𝐠: Built with Vite for a smooth dev experience and used ES modules to keep the codebase clean.  • 𝐀𝐮𝐝𝐢𝐨 𝐀𝐫𝐜𝐡𝐢𝐭𝐞𝐜𝐭𝐮𝐫𝐞: Leaned on the Web Audio API and HTML audio to provide instant feedback, including that "iconic" game-over roast.  • 𝐍𝐞𝐨𝐧 𝐔𝐈: A fully responsive design with a sleek neon aesthetic using custom CSS. 🛠️ 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤: JavaScript (ES6+) | Vite | HTML5/CSS3 | Web Audio API Check out the link 👇 🔗Live: https://lnkd.in/gigMMGGt try to beat your high score, and try not to get roasted by the sound effect!😀 #WebDevelopment #JavaScript #ViteJS #FrontEnd #CodingProject #SoftwareEngineering #SimonSays #ProgrammingHumor #OpenSource

Behind the Screen – #32 Do you know? In JavaScript, almost everything runs on a #SingleMainThread. The main thread is responsible for: 👉 Executing JavaScript code   👉 Updating the DOM   👉 Handling user interactions (clicks, inputs)   👉 Rendering the UI  Since there is only one #MainThread, it can do only one task at a time. If a heavy task runs on the main thread: 👉 The UI becomes unresponsive   👉 Clicks and inputs are delayed   👉 The page may feel frozen  That’s why long operations should not block the main thread. Modern apps try to: • Break tasks into smaller #chunks   • Use #asynchronous operations   • #Offload heavy work when possible  🔥 A smooth user experience depends on keeping the main thread free. #javascript #webdevelopment #frontend #performance #softwareengineering

Stop over-engineering your dropdowns with JavaScript. 🛑 I’ve realized that for most navigation menus, JS is often a "nice to have" that adds unnecessary weight. My go-to approach? The Nav Toggle + CSS combo. Why I’m ditching JS for dropdowns: Performance: CSS transitions are handled by the browser’s compositor—smoother and faster. Reliability: Your menu won't break if a script fails to load or the user has JS disabled. Clean Code: No more eventListeners or toggling classes just to show a simple menu. A hidden checkbox or a focused element does the job perfectly. Don't get me wrong—JavaScript is vital for complex logic. But for a simple UI interaction? Keep it lightweight. Keep it CSS. Where do you stand? Are you Team CSS-only for the speed, or Team JS for the extra control? Let’s settle this in the comments! 👇 #WebDevelopment #CSS #JavaScript #Frontend #CodingTips #CleanCode

A new JS library just dropped yesterday that might change how we think about text layout on the web. 🔤 pretext : pure TypeScript, measures text with zero DOM reflow, zero getBoundingClientRect : zero layout thrashing. Just the browser's own font engine, exposed properly at last. To see what it unlocks, I built a playable DOOM-style ASCII dungeon in the browser on day one. 🎮 Every character placed with exact proportional width. Every frame. No CSS. No DOM reads. 🕹️ Play it: doom-pretext.netlify.app 📦 Try it: https://lnkd.in/g7qXYSAg Sometimes the most important foundational tools ship quietly. This one deserves more noise. #Frontend #WebDev #CreativeCoding #CSS #TextLayout #OpenSource #UIEngineering #Canvas #WebAnimation #Innovation

My Lighthouse Audit Checklist Before any release on Cloudshot, I run this. Every time. 👉 Images: → All images use next/image → WebP format served where supported sizes prop set correctly → Above-fold images NOT lazy loaded 👉 JavaScript: → Route-based code splitting active → No full-library imports (lodash, moment, etc.) → Dynamic imports for heavy components (charts, editors) → No unused dependencies in bundle 👉 CSS: → No render-blocking stylesheets → Critical CSS inlined → Tailwind purge configured correctly 👉 Fonts: → font-display: swap set →Fonts self-hosted or preloaded → No flash of unstyled text (FOUT) 👉 Runtime → No layout shifts on load (CLS < 0.1) → Interaction response under 200ms (INP) → No long tasks blocking main thread This checklist took us from Lighthouse 61 → 94. Save it. Run it before every deploy. #WebPerformance #NextJS #ReactJS #CoreWebVitals #FrontendEngineering #Uber

This image explains how the JavaScript map() function works to create images dynamically from an array. It shows that map() loops through a list of image paths, creates a new <img> element for each item, and then appends those images to a webpage. The diagram visually demonstrates the step-by-step process from array → mapping → generated images → displayed on the page. 🚀 #JavaScript #WebDevelopment #LearnToCode #Frontend
