I recall that "group" is related to a different context, but I can't quite remember how it fits in with shared variable states. I hope I can figure it out during the exam!

I’m a bit confused about the difference between "datastore" and "AppSpace." I remember they both deal with state management, but which one is for shared variables?

I feel like we practiced a similar question where we had to choose the right persistence mode. I think "AppSpace" might be the right answer, but I could be wrong.

I think I remember something about persistence modes, but I'm not entirely sure which one applies to shared variables in an AppSpace.

I vaguely recall that "group" might relate to a different context, but I can't remember the details. I hope I chose the right option!

I feel like "datastore" is more for database interactions, so I’m leaning towards "AppSpace" for this one, but I’m not completely confident.

I think I came across a similar question in practice, and I want to say it was about using "AppSpace" for shared state, but I could be mixing it up.
