/**
 * @description
 * Combines reducers for individual features into a single reducer.
 *
 * You can use this function to delegate handling of state transitions to multiple reducers, each acting on their
 * own sub-state within the root state.
 *
 * @param reducers An object mapping keys of the root state to their corresponding feature reducer.
 * @param initialState Provides a state value if the current state is `undefined`, as it is initially.
 * @returns A reducer function.
 *
 * @usageNotes
 *
 * **Example combining two feature reducers into one "root" reducer**
 *
 * ```ts
 * export const reducer = combineReducers({
 *   featureA: featureAReducer,
 *   featureB: featureBReducer
 * });
 * ```
 *
 * You can also override the initial states of the sub-features:
 * ```ts
 * export const reducer = combineReducers({
 *   featureA: featureAReducer,
 *   featureB: featureBReducer
 * }, {
 *   featureA: { counterA: 13 },
 *   featureB: { counterB: 37 }
 * });
 * ```
