My main goal is to help you understand how Promises in JavaScript work and become an expert in this topic. This course was specifically designed for those who are learning Promises from scratch or improving their skills in using Promises.

JavaScript is asynchronous by its nature. Creating event handlers, making HTTP requests, interacting with the DOM, working with databases – all these operations are asynchronous. Promises make all this stuff a lot easier to deal with. Especially if you need to handle multiple asynchronous operations in your code.

Promises are widely used in all kinds of JavaScript applications. This is a relatively new concept which you need to learn, and this course will help you with that. After watching this course you will be able to work with different kinds of asynchronous JavaScript operations using Promises.Who this course is for:

  • Everyone who wants to learn JavaScript Promises
