jiggery-pokery with switch/case and %W

Courtenay : December 20th, 2005

OK, here's a silly way of getting a little closer to Ruby's way of thinking with javascript. Maybe someone's already done this (flgr..?) but I'm putting this puppy up for adoption anyway. First up, we have %W operator. 

irb> %W' one two three '
=> ['one','two','three']

javascript> function $W(str) { return $A(str.split(/\s+/)); }
then, case 

ruby: 
case foo:
 when 1,2,3:
   # stuff
 when 'four','five','six':
 else:
  # other stuff
end

javascript:

function stuff(arg) {
  switch(true) {
    case ($W('one two three').include(arg)):
      stuff;
      break;
    case ($W('four five six').include(arg)):
       other stuff;
       break;
    default:
      break;
  }
}
Wow, this is incredibly haphazard. Hope it /(helps|confuses)/ someone.
