Master Promise.all() for Faster JavaScript Performance

React vs. Vanilla JavaScript: When to use which? One question I get a lot from clients and junior devs: "Should I build this with React or just plain JavaScript?"

JavaScript vs TypeScript 👨💻⚔️ 🟡 JavaScript → Dynamic → Flexible → Faster to start → Runtime errors 🔵 TypeScript → Strongly typed → Safer code → Better tooling → Compile-time error detection 📌 Truth: Every TypeScript code becomes JavaScript at the end. If your codebase is growing, TypeScript saves time, not wastes it. 💬 JS or TS — what do you prefer and why? #javascript #TypeScript #CodingLife #SoftwareEngineering #WebDev #LearnToCode

Every senior developer I've met secretly hates JavaScript but keeps using it because there's no real alternative for the browser. It's not a choice. It's a hostage situation. 💀 TypeScript is just JavaScript with a blindfold on 😂 it doesn't fix the chaos underneath. Prove me wrong 👇 #JavaScript #TypeScript #SoftwareEngineering #HotTake

Most JavaScript developers don’t understand the Event Loop. They memorize rules and guess outputs. And that’s exactly why: - Promise beats setTimeout - await “pauses” code but not the way you think - setImmediate suddenly runs first - production bugs feel random The Event Loop isn’t magic. But the way it’s taught usually is ❌ So I broke it down the way I wish I had learned it: → real code → real debugging → zero hand-waving If you’ve ever been confused by async behavior or struggled with Event Loop interview questions, this will click. 🎥 Watch here: https://lnkd.in/dsgF5uJn (Warning: you’ll stop guessing outputs after this.) #JavaScript #NodeJS #EventLoop #AsyncJavaScript #JavaScriptInterview #WebDevelopment #SoftwareEngineering

Every JavaScript project ever: Install one “tiny” dependency… Watch your node_modules folder turn into a whole new universe. 🌋 JavaScript developers don’t manage projects— we manage dependencies that have dependencies that have dependencies. 😅 #JavaScript #WebDevelopment #CodingHumor #DevelopersLife

Just watched this eye-opening video on Asynchronous JavaScript and the Event Loop by Akshay Saini (Namaste JavaScript Ep. 15)! 🚀 If you're into JS, this is a must-watch. Key takeaways: ✅ Call Stack Magic: Handles synchronous code like a boss – push, execute, pop. But for async? It delegates to Browser Web APIs. Web APIs in Action: Think setTimeout, fetch, or event listeners. They schedule callbacks without blocking the main thread. ✅ Event Loop – The Gatekeeper: Constantly checks if the call stack is empty, then pushes tasks from Callback Queue (macrotasks like timers) or Microtask Queue (higher priority for Promises, etc.). ✅ Micro vs. Macro: Microtasks (e.g., .then()) run before macrotasks, explaining why fetch might resolve before a setTimeout(0). ✅ Watch Out for Starvation: If sync code hogs the stack, async callbacks wait forever. And don't forget to remove unused event listeners to avoid memory leaks! This cleared up so many confusions for me on how JS fakes concurrency in a single-threaded world. Highly recommend – full of code examples and deep dives. What's your biggest JS async gotcha?

I think real projects have finally convinced me… it’s time to move from JavaScript to TypeScript. 😅 After spending hours chasing weird bugs, unexpected errors, and those classic moments of “why is this even undefined?”, I realised something. JavaScript gives you a lot of freedom… Sometimes a little too much freedom. Working on real applications made me appreciate how useful type safety can be. Catching problems earlier, cleaner code, and fewer surprises at runtime sounds like a pretty good deal. So from now on, I’ll be using TypeScript more in my projects. Not because JavaScript is bad — but because my future self will probably thank me when debugging at 2am. #JavaScript #TypeScript #WebDevelopment #SoftwareEngineering #DevLife

Why JavaScript Isn’t Truly Asynchronous We often say JavaScript is asynchronous. Technically… it’s not. JavaScript is single-threaded and synchronous. Async behavior comes from the environment (Web APIs) and the event loop. • Code runs on the call stack • Async tasks move to Web APIs • Completed tasks go to a queue • The event loop pushes them back when the stack is free Understanding this changed how I think about async logic — especially in React. Still diving deeper into callbacks, promises, and the event loop.

🚀 JavaScript ES6 – Day 2 Today I practiced forEach() and map() in JavaScript. I learned that forEach() is used for looping through arrays, while map() is used to create a new transformed array. 🔹 Main Difference: forEach() == does NOT return a new array map()== returns a new array Small steps every day to improve my JavaScript and React skills. #JavaScript #ES6 #LearningJourney #FrontendDeveloper #ReactJS
