Array vs object tuple (v4)

Revision 4 of this benchmark created on

Setup

var objs = []
  var arrx = [];
  var arry = [];
  
      for(i = 0; i < 10000; i += 1) {
          var o = {x:Math.random(), y:Math.random()};
          objs[i] = o;
          arrx[i] = o.x;
          arry[i] = o.y;
      }

Object

	var resultY=1;
	for(i = 0; i < arr.length; i++) {
		resultX = Math.sqrt(resultX) * Math.pow(arr[i].x*10, 4);
		resultY = Math.sqrt(resultY) * Math.pow(arr[i].y*10, 4);
	}
	return resultX + resultY;
