Say I have this object

var foo {
   "name":"bar"
   "width":600
}

and I want to add another element that references a value within the 
object itself. eg

var foo {
   "name":"bar"
   "width":600,
   "height": width * 2
}

Both
   "height": this.width * 2
and
   "height": foo.width * 2

return errors or undefined.


How do I reference to the object itself within the object?

Or should it be done line this

var foo {
   "name":"bar"
   "width":600
}
foo.height = foo.width * 2;
