javascript variable reference/alias

Question

Is it possible in javascript to assign an alias/reference to a local var someway?

I mean something C-like:

function foo() {
  var x = 1;
  var y = &x;
  y++;
  alert(x); // prints 2 
}

= EDIT =

Is it possible to alias arguments.callee in this code?:

function foo() {
  arguments.callee.myStaticVar = arguments.callee.myStaticVar || 0;
  arguments.callee.myStaticVar++;
  return arguments.callee.myStaticVar;
}

Answer 1

In JavaScript, primitive types such as integers and strings are passed by value whereas objects are passed by reference. So in order to achieve this you need to use an object:

// declare an object with property x
var obj = { x: 1 };
var aliasToObj = obj;
aliasToObj.x ++;
alert( obj.x ); // displays 2
