Joe asks:

But You Promised?!

Given my preference for web standards, you might be wondering why we’re not using a Promise/A+ compatible object to manage our identity information. Since Promises aren’t available in all browsers yet, I’m falling back to Deferred objects because I know they’ll work, and I’m trying to limit the tools I use in this tutorial.

However, in jQuery 3, Deferred objects will be Promise/A+ compatible. So when that’s released, even if ECMAScript 6 hasn’t made its way into all the browsers yet, we’ll be able to use a web standard to manage these chained requests. Unfortunately, at the time of this writing, jQuery 3 is still in Alpha and not suitable for use in this tutorial.
