Course of Asynchrony in JavaScript

💸 First lesson available without registration 💸

In this course, we will take an in-depth look at how asynchrony works in JavaScript, explaining how to overcome common challenges when working with asynchronous code. You will learn about callbacks, promises, async/await and much more. Additionally, we will see how promises can help you avoid "callback hell" and how async/await can make your code cleaner and easier to understand.

But we won’t stop at the basics. We will delve into the event loop and show you when and how to use the different promise methods. We will also see how to effectively handle errors in an asynchronous environment, which is fundamental to avoid headaches in the future.

Moreover, throughout the course we will demonstrate how to apply all this in real situations, so you can see how to put these concepts into practice. By the end of the course, not only will you have a solid understanding of asynchrony, but you will also be able to manage it efficiently in any JavaScript or TypeScript project (because yes, we will also cover some typing).

If you are already familiar with JavaScript but feel that asynchrony gives you problems or can’t break free from the influences of other languages you know, this course may be just what you need.

With this course, you will learn to:

🚀 Efficiently handle asynchrony in your JavaScript code
