Question

Object.observe cannot be called on the global proxy object

When trying to observe the window object (in a browser environment) or the global object (in Node), a TypeError should be thrown with the above message.

That's interesting, because I have primarily considered Object.observe as alternative to Gecko-only Object.prototype.watch(). What is the reason behind that?

I can only guess it was for performance reasons.

Yes, this makes sense, thanks.
