UI is reactive, not state. You push changes to state and UI reacts to it.

A derived state is certainly reactive.

Of course you can have reactive state, your complaint however was:

"The react in react stands for reactivity, however it is not." [because] "Its entire state management is not reactive"

React is primarily an UI library, not full state management library. And its UI is reactive.

Agreed, the OP said that the r in rxjs stands for reactivity, so my point was the the names have little bearing on the actual design patterns achieved with the libs

Ah, now I see what you meant.
