Decorators:
Why is there so much fuss about #decorators (typescript) when #HigherOrderFunctions can do the same thing & have been available in #javaScript forever.

If you want to simulate OOP in #js & use the elusion that inheritance is good for js code base then be my guest & use decorators. 😀

Or use a simple shortcut:

http://str.map &:to_i

You can find more details in Ary's post.
It has obvious advantages in comparison to the Ruby version.

http://str.map{|string| http://string.to_i}
