Hi Dmitry! Thanks for your reply!

I understand that legacy codebases are gonna have classes. Since classes & hooks basically work together, I don’t know why anyone would write much new code without using hooks, because it simplifies event handling so much.

On the other hand, it is a bit of a black box… and I have no idea how to handle that “bubbling problem” when you click on the innermost box but want it handled by the outermost box using React Hooks. :-)
