By the way, how does it break the cycle?
Like I was saying before, node_ptr enlists each pointee object to the
associated root_ptr and when the root_ptr is destroyed then everything
gets wiped out.
See above. Your answer is "it doesn't break the cycle".
Right. And from first hand experience I can report: I've tried hard to
make a deterministic and quick deletion work in a JS engine (through
reference counting, etc.) but always ended up with leaks.
The scope of JS objects is sometimes also not limited to a single
container like a HTML page. Often data can be passed/accessed to/from
other containers. Thus breaking the concept of a isolated roots.
