Difference between a Store and Transition Actor

[ninjz]

I'm struggling to see the difference between a Store and Transition actor. They seem to pretty much be the same thing from what I can see besides the interfaces being a little different and the naming.

Is there a particular scenario where we should be using one over the other?

They are pretty similar. Transition function actors are part of XState, whereas stores are something separate, but easily converted to an XState transition function actor. Also, a transition function is a bit more flexible, since it's just a plain function.
