What type of loops do you use?

Well not sure about this, isn't x=0 faster than `i++, but let's compare the empty loops.

function forLoopV2(){
      for (i = 0; i < LOOPS; i++) {}
}

function whileLoopV2(){
      var i = LOOPS;
      while (i--) {}
} 

>run(forLoopV2)
=1.96909236907
>run(whileLoopV2)
=0.91626548767

Any way it is clear that while loops are faster than for loops.
