var emulatebind = function (f, context) {
  var curriedArgs = Array.prototype.slice.call(arguments, 2);
  if (curriedArgs.length) {
    return function () {
      var allArgs = curriedArgs.slice(0);
      for (var i = 0, n = arguments.length; i < n; ++i) {
        allArgs.push(arguments[i]);
      }
      f.apply(context, allArgs);
    };
  } else {
    return createProxy(f, context);
  }
};

function createProxy(f, context) {
  return function () {
    f.apply(context, arguments);
  }
}

var i = { i: 0 };

var f = function () {
  this.i = Number(""+Math.random());
};

    function bind(fn, ctx) {
        return function() {
            return fn.apply(ctx, arguments);
        };
    }


</script>

Setup

var binded = f.bind(i);
    var emulated = emulatebind(f, i);
    var simple = bind(f, i);;
    var self = function() {
        i.i = Number(""+Math.random());
    }

Teardown


    i.i = 0;
