Syncing Notifications Across Browser Tabs with JavaScript

💡 Did You Know? JavaScript’s event loop processes tasks, microtasks, and rendering in different phases. Because of this, Promise callbacks (microtasks) run before the browser paints the next UI frame. 🌀 This is why async code with promises often executes sooner than expected. Understanding this behavior helps prevent UI glitches, race conditions, and timing bugs while building fast, responsive web apps. Mastering the event loop can greatly improve debugging and performance optimization. 🚀 #Devoticlabs #JavaScript #Didyouknow #AsyncJS #CodingTips

#Hello #Connections 👋 #100DaysOfCodeChallenge | #Day38 🚀 Project: Notes App 📌 What I built Today I built a simple and interactive Notes App where users can create and manage notes directly in the browser. Users can add a note with a heading and details, view it instantly in the notes section, and delete notes when they are no longer needed. 🛠 Technologies Used HTML5 CSS3 Tailwind CSS JavaScript (DOM Manipulation & Event Handling) ⚠ Challenge I faced Dynamically creating note cards and updating the UI whenever a note is added or deleted. ✅ How I solved it Used JavaScript arrays to store notes and a render function to dynamically generate note cards in the DOM whenever the notes list changes. 💬 Open to feedback and suggestions 🚀 🔗 Project link in comments 👇 🙏 Code Of School Avinash Gour | Ritendra Gour #FrontendDeveloper #JavaScript #HTML5 #CSS3 #TailwindCSS #WebDevelopment #100DaysOfCode #DeveloperJourney

Have you ever opened a webpage and noticed that the content appears instantly… but the buttons don’t work for a moment? Recently I was reading about 𝗥𝗲𝗮𝗰𝘁 𝗛𝘆𝗱𝗿𝗮𝘁𝗶𝗼𝗻, and it made me pause for a moment. When we build apps with React frameworks like 𝗡𝗲𝘅𝘁.𝗷𝘀, the page you see in the browser is often already rendered on the server. So when the page loads, the content appears very fast. You can read the text. You can see the buttons. But something interesting is happening at that moment. The page is actually 𝗷𝘂𝘀𝘁 𝗛𝗧𝗠𝗟. Buttons are visible, but the logic behind them isn’t active yet. Event handlers are not attached. State isn’t working. Then 𝗥𝗲𝗮𝗰𝘁 loads in the browser and starts connecting the JavaScript logic to that already rendered HTML. That process is called 𝗵𝘆𝗱𝗿𝗮𝘁𝗶𝗼𝗻. It’s basically the moment when a static page becomes a fully interactive React application. Understanding this small concept will help you to see why SSR makes pages feel faster, and also why sometimes we see 𝘩𝘺𝘥𝘳𝘢𝘵𝘪𝘰𝘯 𝘮𝘪𝘴𝘮𝘢𝘵𝘤𝘩 warnings.

Built a simple Counter App using HTML, CSS, and JavaScript. Increase ➕ Decrease ➖ Reset 🔄 — works similar to cart quantity updates. This project helped me understand DOM manipulation and dynamic value updates. GitHub Repository : https://lnkd.in/gZzUcGWT Live Demo : https://lnkd.in/gYbGruAM #JavaScript #Frontend #Learning

🚀 Just Built a Sticky Notes Web App using HTML, CSS & JavaScript! I recently created a simple Sticky Notes application that allows users to quickly write and manage notes directly in the browser. ✨ Key Features: • Create unlimited sticky notes • Edit notes in real time • Delete notes instantly • Notes automatically saved using localStorage • Clean and simple UI layout 💡 What I learned while building this project: DOM manipulation in JavaScript Handling events like click and input Using localStorage to persist data after page refresh Dynamically creating and updating elements This project helped me understand how front-end apps manage state and user interactions without a backend. 🔗 GitHub Repository: https://lnkd.in/gZGtkcuG I’m continuing to build more mini projects to strengthen my JavaScript and frontend development skills. #WebDevelopment #JavaScript #HTML #CSS #FrontendDevelopment #CodingJourney #100DaysOfCode #GitHub #kccitm

🚀 Understanding useNavigate in React (Simple Explanation) While working with React Router, I came across a very useful hook — useNavigate() 👉 It allows us to navigate between pages programmatically instead of using links. This is super helpful in real-world scenarios like: • Redirecting after login/signup • Navigating after form submission • Handling protected routes 💡 Example: import { useNavigate } from "react-router-dom"; const navigate = useNavigate(); const handleLogin = () => { navigate("/dashboard"); }; 🔥 Things I found interesting: • No need for manual link clicks • Can pass data between pages • Can control browser history (e.g., prevent going back) • Supports forward/back navigation This small hook makes applications feel more dynamic and user-friendly 💻 Currently improving my React skills and building real-world projects.

Just shipped my Day 17/30 JavaScript challenge: a fully functional To-Do List app! Built with vanilla JS, this project showcases DOM manipulation, event listeners, and dynamic element creation in action. Features include adding tasks, marking them complete with a strikethrough effect, deleting individual items, and clearing everything at once. The sleek UI is fully responsive and built with pure HTML, CSS, and JavaScript. no frameworks, just core fundamentals. Tech topics covered: querySelector, innerHTML, createElement, addEventListener, and event delegation. From image uploaders to task managers, each project peels back another layer of web development.
