Short presentation on CoffeeScript for a lunch and learn
Just a short presentation on CoffeeScript that I gave for a Hashrocket lunch & learn.
Probably out of date by now, done around version 0.9.0 (or so?)
Feel free to fork, revise, and issue pull requests. Or reuse personally. Or make fun of me.
Cheers
