This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.
Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:
getTweetsFor("domenic", function (err, results) {
// the rest of your code goes here.

Everyone who's reading this, please leave your opinion/ideas/proposals as a comment for a better world!
Most of you guys read Josh' proposals to make components more reusable, I think. Now, reading through this proposals definitely gives a feeling that this is the right way. Anyways, If you haven't read it yet, you should.
So Josh shows us, how angular apps can be structured in a better and more reusable way. Reusability is a very important thing when it comes to software development. Actually the whole angularjs library follows a philosophy of reusability. Which is why you able to make things like:

| In an HTTP2 world, delivering multiple small individually cachable | |
| and executable scripts can be more efficient than one big | |
| concatenated script. Can we better prepare for this? Can it be | |
| done in a way that works with existing JS files? | |
| Imagine a page that had 4 interactive modules, all of which | |
| depended on a couple of utility scripts. We could progressively | |
| add behaviour to the page by executing the 'action' scripts | |
| as soon as they download & the utilities have executed. |

| // Currently supports Google Analytics, Boomerang and SOASTA mPulse | |
| // In the case of boomerang, you will need to map the event names you want reported | |
| // to timer names (for mPulse these need to be custom0, custom1, etc) using a global variable: | |
| // rumMapping = {'aft': 'custom0'}; | |
