Perhaps I'm just a bit dumb here, but a few of these comments confused me.

Perhaps I'm not understanding the second comment fully... This behavior is completely counter to how Javascript closures work in my mental model. I'm trying to figure out how a state hook differs in execution from a normal variable in module scope.
How does it differ from this [1] example.
