The Event Loop Concept and Asynchronous Development in JavaScript

avaScript is easy when all you need is a simple working interface. The problems begin when the interface becomes more complex. Here you need to have a deeper understanding of JavaScript. It is important that even a large and  complex interface remains fast and responsive. Responsiveness is usually achieved through the use of asynchronous functions. This means that you can let your code do several things at the same time without stopping or blocking the main thread.

In this article, I will try to tell you as simply as possible about the work of asynchronous in JavaScript. At all interviews in my life, I have been always asked this question. When you start learning JS, it can seem daunting but in reality, everything is much simpler.

How does the Event Loop work?

Event Loop is one of those things that every JavaScript developer encounters in one way or another. JavaScript provides a concurrency model based on an event loop, which executes the code, collecting and processing events, and performs queued sub-tasks.

Let’s look at an example of a set timeout:

I think it’s not difficult to guess what sequence these logs will be called in. Let’s check.
