Redux and the New Mob X State Machines

Roxanne Jones: I know some people are going to think this is like the new Redux or mob x. But in fact, X state isn't really a replacement for either of those since it doesn't try to manage your entire state. It's just a pure function that you say, here's my current state and here's the action that just happened. What's the next date? That's the only thing it answers. And so I actually really appreciate what Redux has done for the JavaScript community.
