Ever struggled with messy import paths using baseUrl hacks? 🤔 TypeScript 6 introduces subpath imports - a web standard approach that replaces clunky baseUrl configurations with cleaner, more maintainable import statements. The Problem: Traditional baseUrl requires complex path mappings and can break tooling. The Solution: Subpath imports follow Node.js specification for cleaner, tooling-friendly imports. Key Benefits: → Aligns with web standards → Replaces deprecated baseUrl → Works across build tools → Cleaner, more readable imports → Better IDE support What's your favorite TypeScript 6 feature so far? 💬 #TypeScript #TypeScript6 #WebStandards #JavaScript #DeveloperTips

🚀 Account Page – Profile Edit Flow (Full Stack Implementation) In this video, I’m showcasing how the profile edit system works in my Documents Request Management System. • Secure authentication with JWT • Server-side validation • Protected account route • Real-time profile update flow • Clean backend–frontend integration This is not a tutorial — just a walkthrough of how the logic works behind the scenes. Building with real-world structure and security in mind. 💻 GitHub Repo link: https://lnkd.in/gRGT_Gdv #FullStack #Nextjs #WebDevelopment #Authentication #BuildInPublic #javascript #typescript #jwt

JavaScript is single-threaded, but asynchronous behavior is managed by the Event Loop. 👉 Execution Order: 1️⃣ Call Stack – Executes synchronous code 2️⃣ Microtask Queue – Promises (High Priority) 3️⃣ Macrotask Queue – setTimeout, setInterval, DOM events (Low Priority) The Event Loop processes all microtasks before executing the next macrotask. That’s why Promise callbacks run before setTimeout — even with 0ms delay. Understanding this mechanism is crucial for writing efficient and non-blocking JavaScript applications. #JavaScript #EventLoop #AsyncJS #FrontendDeveloper #WebDevelopment 🚀

Vite 8 just landed 🚀 Vite 7 used two tools: esbuild (dev, written in Go) Rollup (production, written in JS) Vite 8 uses a single bundler: Rolldown (written in Rust). The impact: ⚡ 10–30× faster production builds ⚡ Example: 46s → 6s build time ⚡ More consistent behavior between dev and prod ⚡ Rollup-compatible plugin ecosystem Upgrade : npm install vite@latest Requires Node.js 20.19+ or 22.12+ If you're still on Vite 7, it's a good time to test the upgrade.

Day 5 of 30: Tracking time with JavaScript! For today’s #30DaysOfJavaScript challenge, I built a real-time Digital Clock. This project was a great way to dive into how the browser handles time and asynchronous updates. Check it out here: https://lnkd.in/dc3aAeBt Key Technical Highlights: => Real-time: Used setInterval() to keep the clock ticking. => Localized: Used .toLocaleString() to ensure the format matches the user's location. => Building small every day leads to big results. On to Day 6! #WebDevelopment #JavaScript #CodingChallenge #Netlify #BuildInPublic #FrontEndDev

JavaScript is single-threaded, but async code doesn’t just run whenever it feels like it. The engine processes: The call stack Then microtasks (Promises) Then macrotasks (setTimeout, etc.) Which means this: console.log("Start"); setTimeout(() => console.log("Timeout"), 0); Promise.resolve().then(() => console.log("Promise")); console.log("End"); Logs: Start End Promise Timeout Even with 0ms, setTimeout waits until the microtask queue is empty. Once I understood that, async bugs stopped feeling random. The event loop isn’t just trivia, it’s how you reason about timing instead of guessing. #JavaScript #EventLoop #AsyncProgramming #WebDevelopment

If you understand this, you understand async JavaScript. There are TWO important queues: 1️⃣ Microtask Queue 2️⃣ Macrotask Queue Example: console.log("Start"); setTimeout(() => console.log("Timeout"), 0); Promise.resolve().then(() => console.log("Promise")); console.log("End"); Output: Start End Promise Timeout Why? Execution order: Run synchronous code Empty Microtask queue Take one Macrotask Repeat Microtasks include: • Promise callbacks • queueMicrotask Macrotasks include: • setTimeout • setInterval • I/O Promise always runs before setTimeout. This is critical when debugging race conditions. #javascript #eventloop #webdevelopment #frontend

🚀 React Tip: Stop Writing Long useEffect Fetch Logic Instead of writing complex useEffect + useState code for API calls, use SWR (Stale-While-Revalidate). It gives you: ⚡ Faster UI with caching 🔄 Automatic data revalidation 🧹 Cleaner & shorter code Less boilerplate. More performance. #React #WebDevelopment #Frontend #JavaScript #CodingTips

day7: javascript: single threaded JavaScript stays non-blocking by executing synchronous code immediately while offloading asynchronous tasks, like setTimeout(), to the browser's Web APIs. Once the main stack is clear and the timers expire, the Event Loop pushes those callbacks back into execution to finish the job.
