createFeatureSelector: {
    <T>(featureName: string): MemoizedSelector<object, T>;

function createReducer

createReducer: <S, A extends Action = Action>(
    initialState: S,
    ...ons: ReducerTypes<S, ActionCreator[]>[]
) => ActionReducer<S, A>;

Creates a reducer function to handle state transitions.
Reducer creators reduce the explicitness of reducer functions with switch statements.
Parameter initialState
Provides a state value if the current state is undefined, as it is initially.
Parameter ons
Associations between actions and state changes.
Returns
A reducer function.
- Must be used with ActionCreator's (returned by createAction). Cannot be used with class-based action creators. - The returned ActionReducer should additionally be wrapped with another function, if you are using View Engine AOT. In case you are using Ivy (or only JIT View Engine) the extra wrapper function is not required.
**Declaring a reducer creator**
export const reducer = createReducer( initialState, on( featureActions.actionOne, featureActions.actionTwo, (state, { updatedValue }) => ({ ...state, prop: updatedValue }) ), on(featureActions.actionThree, () => initialState); );
**Declaring a reducer creator using a wrapper function (Only needed if using View Engine AOT)**
const featureReducer = createReducer( initialState, on( featureActions.actionOne, featureActions.actionTwo, (state, { updatedValue }) => ({ ...state, prop: updatedValue }) ), on(featureActions.actionThree, () => initialState); ); export function reducer(state: State | undefined, action: Action) { return featureReducer(state, action); }
