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written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.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

rem and em units are computed into pixel values by the browser, based on font sizes in your design.
em units are based on the font size of the element they’re used on.
rem units are based on the font size of the html element.
em units can be influenced by font size inheritance from any parent element
rem units can be influenced by font size inheritance from browser font settings.

Use em units for sizing that should scale depending on the font size of an element other than the root.
Use rem units for sizing that doesn’t need em units, and that should scale depending on browser font size settings.
