Revision 21 of this benchmark created on

Setup

function Foo(x) {
    this._x = x;
  }
  
  Foo.prototype.getValue = function() {
    return this._x + 5;
  };
  
  var self = new Foo(7);
  
  var boundFn = (function(a, b) {
    return this.getValue() + a + b;
  }).bind(self);
  
  var selfFn = function(a, b) {
    return self.getValue() + a + b;
  };
