In Ruby I think you can call a method that hasn’t been defined and yet capture the name of the method called and do processing of this method at runtime.
Can Javascript do the same kind of thing ?

The ruby feature that you are explaining is called “method_missing” http://rubylearning.com/satishtalim/ruby_method_missing.htm.
It’s a brand new feature that is present only in some browsers like Firefox (in the spider monkey Javascript engine). In SpiderMonkey it’s called “__noSuchMethod__” https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Object/NoSuchMethod
Please read this article from Yehuda Katz http://yehudakatz.com/2008/08/18/method_missing-in-javascript/ for more details about the upcoming implementation.
