You "scaling" is just a syntactic sugar to the underlying package/module solution. In js/coffee the syntax just don't care about it, and you use package/module with a library. Most of the semantics or environment stuff are translated into function calls at last. Then the difference becomes the syntax again: how to use that function? Call it directly or translate a syntax? I like coffee because it is practical scripting: Need code completion? Don't repeat yourself. Can't code without IDE? Make the language easier to use then you ain't gonna need it. Some people just can't believe a language can be that good without IDE, but remember: you interact with IDE through a language on keyboard/mouse too.
