Revision 42 of this benchmark created by yzsolt on

Description

Test different access method to an object property

Setup

var obj = function() {
       this._x = 0;
      };
      
      var acc = 0;
      
      funct = {
       get: function() {
        return this._x
       },
       set: function(value) {
        this._x = value
       }
      }
