useReducer<State, Action> function

Store<State, Action> useReducer<State, Action>(Reducer<State, Action> reducer, { required State initialState, required Action initialAction, })

An alternative to useState for more complex states.

useReducer manages a read only instance of state that can be updated by dispatching actions which are interpreted by a Reducer.

reducer is immediately called on first build with initialAction and initialState as parameter.

It is possible to change the reducer by calling useReducer with a new Reducer.
