Show HN: A small, functional state management library

I always click on these and try to find a state management to use with React or similar frameworks, because Redux is horrible and the most famous alternatives are even worse.

To enlight people like me who are going to click this, I must say I had a good experience with https://github.com/andrejewski/raj.

When people say "immutable" they're actually meaning "functional data structures", right? Not JavaScript objects which you are prevented from mutating.

But here and in many other similar libraries it seems that "immutable" actually hold the second meaning.
