const vs var in closures (v6)

Revision 6 of this benchmark created on

Setup

funcs = [];
    funcOrObjs = [];
    count = 10000;
    var getter = function (x) { return function () { return x; }; };
    for (var i = 0; i < count; i++) {
      funcs.push(getter({num: i}));
      if (i % 2 === 0) funcOrObjs.push(i); else funcOrObjs.push(getter({num: i}));
    }
    result=[];
