Are useMutableSource events automatically batched?

[kirillNevedrov]

Hello,

I've read through this issue #89 to understand how to batch multiple store updates. I see that react concurrent mode will solve that issue, because react will automatically batch multiple setStates. But I've noticed that zustand v4 will use useMutableSource instead of useReducer internally. Is it guaranteed that react in concurrent mode will automatically batch multiple update events from useMutableSource?

1. We don't know yet how uMS behaves when it lands.
2. You can try [v4-experimental] use mutable source (#157) #160 to see the current behavior.
3. I'd expect the behavior of uMS isn't different from that of useReducer.

That said, I'm not 100% sure how batching behaves in concurrent mode...

Thank you for the clarification.
