So, closures are indeed poor man's objects.

  It's storing all the hooked-in functions (methods) and variables (properties) outside the function and associating them with the relevant React view object instance at run-time, which is effectively the hooks' "this". Unless the code's change substantially and in very fundamental ways since it was introduced. It doesn't bring to mind closures, at least as I read it. It very much brings to mind object/class-system implementations.
