Generic objects in CoffeeScript

gistfile1.coffee

NameSpace = NameSpace or {}
NameSpace.ClassName = (options) ->

  # default options
  defaultOpts = ->
  defaultOpts:: =
    some_option: "some value",
    another_option: "another value"

  # private vars
  self = this
  opts = $.extend({}, new defaultOpts(), options)

  # private methods
  something = ->
    # method code

  # public methods
  self.init = ->
    # init code

  return

window.instance = new NameSpace.ClassName()
$ ->
  window.instance.init()

this version doesn't pass in options but you'd overwrite the default with: window.instance = new NameSpace.ClassName({ some_value: "something else" })
