I have this object:

What are the [[Handler]], [[Target]] and [[IsRevoked]] keys? I search for them but cannot see anything. I try to query them with either object.["[[Target]]"] or object.["Target"] but it doesn't work. But object.Target works. What is interesting is that object.Target.Target.Target... also works.

I'm using Firefox. The real data is under object.Target. But I cannot query it with object.Target.values (it will be the same with object.Target.Target. Length is 0), but object.values
