Not sure if those are the same though?

Async, await, iterators, futures etc. are pretty much standard constructs in almost all programming languages / concurrency frameworks.

Whereas Actions, Transitions, Pending State, Reducers etc. are React-specific idiosyncrasies.

I guess that's the main issue people have with React, when you learn it you have to spend so much time to learn all these React-specific constructs and idiosyncrasies that are not transferable anywhere else.
