When I looked into Redux first time (2018 year), my initial (and decision making) reaction was - surely we should have better ways of doing interfaces to global states than string named actions and huge switch statements with loosely typed arguments. Bad interfaces and non-obvious contracts between components and states is one of the reasons why old code can not be understood. I understand Dan. I started straight with Mobx and ended up using Hookstate, which is simpler and faster than Redux and Mobx.

Disclaimer: I am an author but here is the feedback and success story by an external developer, who has switched from Redux to Hookstate.
