RELATES_TOSolution

You don't need to use the same name for both. Tension: it also ships with a new `combineSlices` api. Outcome: in most cases you probably shouldn't deviate unless you have a reason.

AFFECTSRootCause

createSlice passes initialState to createReducer, which attaches getInitialState to the generated reducer

AFFECTSRootCause

The `counterReducer` is receiving an initial state that is a number, but the reducer logic treats `state` as an object and writes/reads `state.counter`, causing `state.counter` to be undefined and producing `NaN` (and potentially nesting like `counter.counter`).

AFFECTSRootCause

createSlice passes initialState to createReducer, which attaches getInitialState to the generated reducer

AFFECTSRootCause

the `name` property of a Redux Toolkit slice has to correspond to the property name of the reducer. Tension: it's just that EVERY single tutorial used the same name for both. Outcome: in RTK 2.0, `createSlice` has a new `reducerPath` option that will default to `name`.

REQUIRESSolution

Use the reducer exported by createSlice in configureStore; the store gets the initial state from that reducer
