A version of Flux on top of Redux with a (hopefully) simpler API. When approaching Redux, for such a simple yet powerful library, there are quite a few concepts to learn including actions, action creators, reducers, stores, middleware, thunks, etc. Furthermore, with so many parts, organizing them becomes a problem (see Ducks).
Redux Command attempts to simplify the number of concepts and also provide an obvious connection between them to promote easier use while still allowing for the full power of Redux.
