In this module of the course, we're going to be walking through the concept of 'Promises' in javascript. Now if you've never worked with javascript promises the concept may seem a little bit foreign.

Now that you have a basic understanding of how to build promises in Javascript. In this guide we're going to extend that knowledge and we're actually going to see how the javascript developers integrated promises to be able to communicate with outside API's when they built the fetch function.

So far in this section of the course, we've analyzed how we can work with promises and Javascript. We've seen how we can create a promise from scratch and how we can implement a resolve and a reject function to see exactly what we want to do when a promise succeeds versus when it fails.
