It's a unfortunate that he doesn't include the equivalent class-based implementations of his logging quiz. Event lifecycles notoriously obscure order of execution, so I'm not sure the alternative is any clearer -- especially not with contrived examples. In my experience with both hooks and classes:

- Hooks require substantially less boilerplate than classes.

- Rendering optimization problems with hooks tend to take more time to identify and to fix.

There are other pros/cons, but these are the ones that affect my work most frequently.
