A better way to react with state

import { BehaviorSubject } from 'rxjs';
export function createState(defaultState) {
    const _state$ = new BehaviorSubject(defaultState);
    return {
        getState() {
            return _state$.getValue();
        },
        setState(state) {
            _state$.next(state);
        },
        state$: _state$.asObservable(),
    };
}
