Javascript Question

javascript variable reference/alias

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;
alert(x); // prints 2

= EDIT =

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

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


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 anotherObj = obj;
alert(obj.x); // displays 2
