About This Episode:
JavaScript may look simple, but under the hood it’s powered by the Event Loop — the secret sauce that lets your code juggle tasks, handle async operations, and keep your apps responsive. In this video, we’ll break down exactly how it works (without frying your brain 🥓).
Here’s what you’ll learn:
📚 Call stack basics – how functions get pushed, popped, and executed
⏱️ Synchronous vs asynchronous execution – what runs now vs what runs later
🕒 Macrotasks – like setTimeout and setInterval
⚡ Microtasks – like Promises and queueMicrotask
🧪 A hands-on demo where we predict and then prove the order of console logs using timers & promises
You’ll finally understand:
✅ Why some logs show up before you expect them
✅ Why promises are “faster” than timeouts
✅ How the browser keeps things efficient, even when you’re spamming microtasks
By the end, you’ll see the Event Loop not as magic, but as your best friend in building smooth, non-blocking web apps 🚀
👉 Watch now and unlock the inner workings of JavaScript’s brain 🧠⚡
