CoffeeScript Style Guide

• Use 2 spaces for indentation, no tabs.
• End each file with a blank line.
• Wrap lines at 80 characters.
• Remove trailing whitespace.

• Space after a comma but not before:

  # Yes
  api_app.factory "ApiService", ($http) ->
  
  # No
  api_app.factory "ApiService" ,($http) ->

• Write constants in all caps, LIKE_THIS.

• Use if/else, not unless/else.

• Use list comprehensions when they fit on a single line:

  # Yes
  result = (item.name for item in array)
  
  # No
  results = []
  for item in array
    results.push item.name

• Use comprehensions for filtering when they fit on a single line:

  result = (item for item in array when item.name is "test")

• Use @property not this.property.
