jQuery vs Underscore Each (v4)

Revision 4 of this benchmark created by Akos Lukacs on

Description

Is jQuery's $.each or Underscore's _.each faster if underscore is going through 53x as many elements?

Would be a fair test, if _(Modernizr), and $(Modernizr) would have the same number of elements...

Check the printed "items in xxx loop:" message...
