State Splitting
Definition
The architectural practice of breaking a monolithic global state object down into smaller, highly focused slices to improve performance and code organization.
Explain Like I'm New
Don't put `ui` state (like is the modal open) in the same slice as `data` state (like the list of users). If they are in the same slice, updating the modal might accidentally trigger components that are watching the user data.
Real World Example
Creating separate files for `authSlice`, `cartSlice`, `productSlice`, and `themeSlice`.
