Checking if an array has some items in coffeescript

Is there some method in coffeescript that returns true when an array has some items in it? Like method in ruby present?:

[].present? false
[1].present? true

According to http://arcturo.github.com/library/coffeescript/07_the_bad_parts.html an array emptiness in coffeescript is determined by its length

alert("Empty Array")  unless [].length

that seems so lame to me.
