Hey folks,

We covered a lot of ground yesterday and I wanted to write up some notes on a few points that helped me get up the CoffeeScript learning curve.

List comprehensions

I spend most of my time in Ruby and ObjC and this is one of those language features I truly envy.

Let's say we have some DOM elements that need to be sortable via drag-and-drop. It'll work like the re-orderable queue on Netflix (if you still get DVDs mailed to you like a chump.)
