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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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

var util = require('util');
var events = require('events');
var redis = require('redis');

var RedisQueueConsumer = function (port, host) {
  events.EventEmitter.call(this);

  this.port = port || 6379;
  this.host = host || '127.0.0.1';
};
