In interest of precision, those are methods, not syntactic sugar.

  and they can be implemented almost identically in Javascript (just use 3.hours().ago() - each one can return a useful value, and have helper methods just like Ruby.)

    although 3.times is probably harder since all ruby methods take an implicit block as last parameter. The prettiest code you could do in node would be 3.times(function(){/code/}) It would be nice if js could rid of the keyword 'function' -- maybe make it a bit shorter like in coffeescript.

      "function" will be gone soon enough - replaced (ok, augmented) in the next version of JS with "#" - so you'll be able to write: #(x) { x * x } instead of function(x){ return x * x; } http://brendaneich.com/2011/01/harmony-of-my-dreams/ http://brendaneich.com/2011/01/harmony-of-my-dreams/ (He indicates that the function change will land in this ((very good)) podcast: http://www.aminutewithbrendan.com/pages/20110303 http://www.aminutewithbrendan.com/pages/20110303)

        Which would make it 3.times(#(i) { /* code */ }). That's not bad at all.

          Gah, line noise. Imagine using that + jQuery: 3.times(#(){ $("#some_id").attr("href").hide(); });
