I don’t understand this.

1) why are we talking about TJSObject? That’s an additional use for..in which is good to know but it’s not an array.

2) Why doesn’t this work with JSArray like you would expect? I mean if a function returns a JSArray of integers for example can’t I use for..in and have the iterator be of type integer? That’s really the question I’m asking.
