prototype vs recreate (v4)

Revision 4 of this benchmark created by Mariusz Nowak on

Description

How speed-wise is relying on prototype

Setup

var Obj = function () {};
  var obj = Obj.prototype = {
    fa: function (a) { return this.fb(a);},
    fb: function (b) { return this.fc(b); },
    fc: function (c) { return c + 1; }
  };
  var cache = [];
  var add2Cache = function (obj) {
    cache.push(obj);
    return obj;
  };

Teardown


    cache = [];

Test runner

Ready to run.
