Author here. I think we might actually be in agreement. My point is that in React you don't formally describe the transition table because (and I think this is where we agree) that's infeasible for an app of any reasonable size.

The observation I'm trying to capture in this post is that even though we don't define a formal transition table, we actually _do_ implicitly define the set of valid (user) transitions for each state via the event handlers we bind into the DOM when our React component tree renders that state.
