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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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.
| // When one has to conform to using Regex, ameliorate the nasties and qualify/quantify as many identifiers as you can :boom: :tada: | |
| // E.g. Self-documenting version of an unmaintainable Regex string | |
| // 1. Break it up into readable functions/vars with doc comments | |
| // 2. Build up the parts back into the final result | |
| // Win. :lion: :gem: | |
