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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

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.

It's with a heavy heart that I announce that Friday, May 31 2013 will be my last day at Heroku.

How can I possibly put into words what Heroku has meant to me these last six years? I can say it was a tremendous experience; or the opportunity of a lifetime; or the greatest thing I have ever been a part of. I can say that Heroku has been my life's work, as I did recently in a public blog post. All of those things are true, but none seem to capture the enormity of what's transpired these past six years.

I tend to focus on mechanical elements of a company: product, code, design, process. But what has surprised me the most at Heroku is that none of these things is the best part. The best part is the team.

I've never had the chance to work with a more singular group of people. Talented, passionate, skilled, dedicated. Most of all, sharing a set of values: elegance, craft, maniacal focus on simplicity; and an uncompromising belief that the future will be made of software, and how that software gets made will shape
