chjj / coffeescript.poem
Created Aug 15, 2011
a poem about coffeescript
View coffeescript.poem
a poem about coffeescript in the style of the lord of the rings:
one does not simply walk into coffeescript
its syntax is guarded by more than just ruby devs
and the significant whitespace is ever present
it is a wasteland barren of curly braces
- riddled with class syntax, postfix conditionals, and operator aliases
the very code you write, is a poisonous fume
not with 10,000 men who knew javascript could you do this

You can’t perform that action at this time.
