createEntityAdapter, combineSlices, reducer composition

In Redux Toolkit, multiple slices can be combined into a single Redux store using the configureStore() function. Each slice manages its own part of the state, and all are added as separate reducers under unique keys.

Steps to Combine Slices

1
Create individual slices for different features (e.g., userSlice, counterSlice).
2
Import all slice reducers into a central store file.
3
Use configureStore() to combine them into one store by passing an object to the reducer field.
4
Each slice’s name (or key in the reducer object) determines its section of the global state.
