Have you ever wondered how JavaScript really handles asynchronous operations?

During my presentation, I will unveil the secrets of the event loop mechanism that powers asynchronous JavaScript. You'll learn what microtasks and macrotasks are, how the browser manages background tasks, and how you can take control of their execution in your code.

I’ll also show you how to effectively use fascinating APIs like requestIdleCallback and discuss the future of asynchrony with the upcoming Scheduler API. All of this will be presented in a practical context, without relying on frameworks or libraries – just pure, classic JavaScript!

If you want to better understand how JavaScript works "under the hood" and learn how to write more efficient code, this presentation is for you.
