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;
}

in 2019 I need to write minified jquery plugins so I need it too this alias and so testing these examples and others ,from other sources,I found a way without copy in the memory of whe entire object ,but creating only a reference. I tested this already with firefox and watching task manager's tab memory on firefox before. The code is:

var {p: d} ={p: document};
console.log(d.body);
