Optimizing React Performance: Debunking Reflow Myths

Recently I built a Typing Speed Test using HTML, Tailwind CSS, and Vanilla JavaScript. Instead of just a pretty UI, I focused on real-time typing mechanics and a smooth mobile experience. 🔎 Features I implemented: • Live WPM & accuracy on every keystroke • Green/red character feedback + moving cursor • Difficulty & mode selection (synced mobile/desktop) • Personal best with localStorage • Confetti on new high score • Fixed bottom restart button • Auto-scrolling text area 🚧 Challenges I faced: • Syncing mobile dropdowns & desktop pills without bugs • Preventing scroll/keyboard jitter on mobile • Accurate real-time stats & efficient DOM updates 💻 Tech Stack: HTML | Tailwind CSS | Vanilla JavaScript | LocalStorage This project leveled up my: • Real-time DOM manipulation • Pure JS state management • Mobile-first responsive design • Cross-device input handling Live demo: https://lnkd.in/gNNS35iy #JavaScript #TailwindCSS #FrontendDevelopment #WebDev

I made a game as a web component using vanilla JS to facilitate dynamic CSS and HTML. This slider puzzle can be placed in html with a <slider-puzzle><\slider-puzzle> tag followed by a <script><\script> that either sources or contains the single js file. Hook it up to a hit key or a button and it will open and close over your page without affecting your layout at all. You can turn any image from your device into a puzzle in a snap and can set the difficulty by adjusting the number of tiles the image is split into and the shuffling algorithm handles the rest. Completely portable, no dependencies no frameworks no build needed. Send a like or a comment and I’ll share the code and a walkthrough how I did it. #html #javascript #css JavaScript

Back to the basics! 🚀 I’m currently spending some time revisiting the core pillars of web development: HTML, CSS, and JavaScript. Even as we move toward complex frameworks, I believe a rock-solid understanding of the DOM and styling is what separates a good developer from a great one. Today’s session: DOM manipulation and refining layouts. It’s amazing how much more you notice when you go back to the fundamentals with a fresh pair of eyes. #WebDevelopment #CodingLife #Frontend #LearningEveryday #JavaScript #HTML #CSS #Programming
