Flux inspired practice

Although zustand is an unopinionated library, here's one of recommended usages.

const useStore = create((set) => ({
  storeSliceA: ...,
  storeSliceB: ...,
  storeSliceC: ...,
  dispatchX: () => set(...),
  dispatchY: () => set(...),
}))

• Create one single store
• Define a store only with set
• Define dispatch functions at the root level of store to update one or more store slices

See Splitting the store into separate slices to define a store with separate slices.
