State Machines - The Solution to Building a React Application

I was a junior developer when I came up with the idea of state machines. It's really interesting in that sort of scenario described is like something we'll all be familiar with. All apps have some sort of event based code, whether we're explicitly coding these events or nots. As far as finite states go, for example, multi step forms or when your application has different behaviors over time are good use cases. But yeah, so I would say applications such as CRUD and even those could use state machines as well.
