Float32Array vs Array (v10)

Revision 10 of this benchmark created by array vs f32 on

Setup

var size = 5000;
    var f32 = new Float32Array(size);
    var arr = new Array(size);
    
    function runf32(){
      for(var i=1; i<size; i++){
        f32[i-1] = f32[i];
      }
    }
    
    function runarr(){
      for(var i=1; i<size; i++){
        arr[i-1] = arr[i];
      }
    }
