ES Modules for Clean JavaScript Apps

Ever wondered how Node.js works behind the scenes? 🤔 In my latest blog, I broke down Node.js internals in a simple way — focusing on the 3 core components: 🔹 V8 Engine (executes JS & manages memory) 🔹 Libuv (handles async tasks & event loop) 🔹 Bindings (connects V8 with system-level operations) Understanding this flow really changes how you look at things like fs.readFile() or setTimeout() 💡 👉 Read the full blog here: https://lnkd.in/g-AbBCiy I’d really appreciate your thoughts, feedback, or any experiences you’ve had while working with event propagation 😊 Hitesh Choudhary | Piyush Garg | Akash Kadlag #JavaScript #WebDevelopment #Blog #NodeJs #Cohort2026 #LearnInPublic #libuv #v8

𝗦𝗶𝗻𝗴𝗹𝗲-𝗧𝗵𝗿𝗲𝗮𝗱𝗲𝗱 𝗝𝗮𝗵𝗮 𝗖𝗮𝗻 𝗛𝗮𝗻𝗱𝗹𝗲 𝗠𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗧𝗮𝘀𝗸𝘀 JavaScript is single-threaded but it can handle multiple tasks efficiently. How? The answer lies in understanding synchronous vs asynchronous behavior. You will learn how to handle tasks in a simple way. Synchronous code runs line by line, one step at a time. - Each task must finish before the next one starts. If one task takes time, everything else waits. Asynchronous code allows tasks to run without blocking the main thread. - Long tasks are handled in the background, and the program keeps running. You can handle tasks like: - Fetching data from an API - Loading a file - Waiting for user input These tasks take time. Asynchronous code helps you handle them efficiently. You can build responsive apps and handle real-world tasks by understanding synchronous vs asynchronous behavior. It helps you understand callbacks, promises, and async/await.

Ever notice your search bar firing an API call on every keystroke? Type “react” and that’s 5 requests. Type a sentence and your network tab cries. The fix is a tiny React hook called useDebounce. It waits until the user stops typing, then returns the final value. One render. One request. Done. No libraries. No dependencies. Drop it into any search input, filter, or autosave field. Snippet here: https://lnkd.in/gHDtaUtJ What React hook do you reach for in every project? #ReactJS #JavaScript #WebDevelopment #ReactHooks #FrontendDevelopment

𝗩𝗨𝗘.𝗷𝗦 𝗠𝗔𝗞𝗘𝗦 𝗗𝗔𝗧𝗔 𝗧𝗥𝗔𝗡𝗦𝗙𝗘𝗥 𝗘𝗔𝗦𝗜𝗘𝗥 You use Vue.js to create user interfaces. It is a JavaScript framework. Vue.js makes it easy to transfer data. You want to learn how to transfer data between templates. Vue.js helps you with this. - It is easy to use - It saves you time - It makes your work easier Source: https://lnkd.in/gxm65wxr

I just deployed a full refactor of my portfolio site. Here's what changed and why. The original was built with vanilla HTML, CSS, and JavaScript. It did the job, but as my skills grew, it stopped reflecting where I actually am as a developer. The new stack: - React - TypeScript - Tailwind CSS - Vite The goal wasn't only to modernize the tech stack. I wanted to challenge myself with TypeScript in a real project setting and build something I'm genuinely proud to share with the world. Always a good sign when refactoring your own old code makes you cringe a little. It means you've grown.

𝗧𝗵𝗲 𝗩𝗶𝗿𝘁𝘂𝗮𝗹 𝗗𝗢𝗠 𝗘𝗻𝗴𝗶𝗻𝗲 You use React, but do you know how it works? Let's break it down. The Virtual DOM is not a performance optimization. It's a programming model where you describe what the UI should look like. The framework figures out the minimal set of changes. - You write UI in HTML, but HTML is a string. - JavaScript can't inspect the tree or compute what changed. - What if you described the structure as a plain JavaScript object instead? We'll build a Virtual DOM engine in 100 lines of vanilla JavaScript. Four functions: - h() to create virtual nodes - render() to mount to the DOM - diff() to compare two trees - patch() to apply changes The engine works in two phases:

Day 25 of my JavaScript journey 🚀 Built a Recipe Finder App using HTML, CSS, and JavaScript, powered by an external API. Features: 🍽️ Search recipes dynamically 🌐 Fetch data from TheMealDB API 📄 Display recipe details in real-time ✨ Interactive and user-friendly UI This project helped me understand how to work with APIs, handle asynchronous JavaScript, and build real-world applications. 🔗 Live Demo: https://lnkd.in/gSAAATzM 💻 GitHub Repo: https://lnkd.in/gBQmmBYJ Moving beyond basic projects and building applications that interact with real data. 💻 #JavaScript #WebDevelopment #FrontendDeveloper #100DaysOfCode #CodingJourney #API

Framework fatigue is real. Every year, a new JavaScript framework promises faster development, cleaner code, and better performance. React, Vue, Svelte… and the list keeps growing. But here’s the uncomfortable question: Are we actually becoming more productive, or just better at relearning the same concepts in different syntaxes? On one hand, modern frameworks have undeniably improved developer experience: - Better state management - Component-based architecture - Rich ecosystems On the other hand: - Constant churn means skills have a shorter shelf life - Teams spend more time migrating than building - “Best practices” change faster than projects can stabilize The result? We risk optimizing for trends instead of outcomes. Most users don’t care what framework you used. They care if the product works, loads fast, and solves their problem. So maybe the real skill isn’t mastering the latest tool, it’s knowing when not to switch. Curious where others stand: Are new frameworks pushing the industry forward, or just creating noise?

JavaScript Promises finally clicked for me today — and honestly, the real-life analogy made all the difference. Think of it like ordering food: • Order placed → Pending • Food delivered → Resolved • Order cancelled → Rejected That’s literally how async code behaves behind the scenes. What I found interesting is how Promises simplify "callback hell" into a much cleaner flow using ".then()", ".catch()", and ".finally()". Still wrapping my head around async/await, but this feels like a solid step forward.
