Do you want to use the difference function of underscore? You can do this:

_.difference([1, 2, 3, 4, 5], [5, 2, 10])

this works in coffeescript.

EDIT

Using an array of objects and comparing the id property

arrayOne = [{id: 1}, {id: 2}]

arrayTwo =[{id: 2}, {id: 3}]



_.select arrayOne, (item) ->

    !_.findWhere(arrayTwo, {id: item.id})
