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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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

JavaScript Code

var str = "hi";

Memory allocation:

Imitate hand-drawn (imperfect) circles using cubic Bézier segments, based on a Bézier approximation to a perfect circle. TLDR: a good approximation to a quarter circle of unit radius is a cubic Bézier curve with control points P₀ = (0,1), P₁ = (c,1), P₂ = (1,c), P₃ = (1,0) where c = 0.551915024494. By varying the points in a sensible way, we can do a good impression of hand-drawn circles.
