Javascript and promises

I wrote a little tutorial a small while back on using promises within Javascript as this seems to be a point of confusion for some, especially those new to promises. The tutorial is not meant to be ultimately comprehensive, but hopefully it should at least be useful -- and it made me polish up a promises library of my own for learning and display purposes. You can get all the code here: https://github.com/fluffynuts/js-promises-tutorial and indeed that repository is what I'm using for the iframe source below, using RawGit. Mainly because it relies on a bunch of Javascript and JSON files to work but also because I'm way too lazy to maintain multiple versions of this and this tutorial may be revisited for a little spit 'n polish on occasion. (EDIT: this entry was updated to include example usage of the ES6 native Promise prototype).
