ES2015 brought a native Promise to the JavaScript standard library. In this course, we’re going to take an in-depth look at how to use promises to model various kinds of asynchronous operations.

First, we’re going to explore how to create promises using the Promise constructor or the Promise.resolve() or Promise.reject() methods. Then, we’re going to see how to chain promises together using .then(), .catch(), and .finally(). We’re going to compare various error handling strategies along the way. We’re going to wrap up this course by taking a look at how to deal with multiple promises using Promise.all() and Promise.race() and how to await a promise using the await operator.

    What did you like about this course?

    Though at times it was moving a bit fast for me, with paying attention to the screen and understanding what was going on. After I have completed this course now I feel pretty good about how promises work in Javascript. Your examples were spot on :). Thank you for taking the time a developing this course to clear the cloud around promises. Promises, this and closures are some of the most confusing aspects of javascript.
