A better way to react with state

import { Subject } from 'rxjs';
import { getActionNames } from '../decorators';
import { effectSymbols, reducerSymbols, immerReducerSymbols, defineActionSymbols } from '../symbols';
const getOriginalFunctionNames = (ayanami) => ({
    effects: getActionNames(effectSymbols, ayanami.constructor),
    reducers: getActionNames(reducerSymbols, ayanami.constructor),
    defineActions: getActionNames(defineActionSymbols, ayanami.constructor),
    immerReducers: getActionNames(immerReducerSymbols, ayanami.constructor),
});
const transformDefineActions = (actionNames) => {
    const result = {};
    actionNames.forEach((actionName) => {
        const actions$ = new Subject();
        result[actionName] = {
            observable: actions$.asObservable(),
            next: (params) => actions$.next(params),
        };
    });
    return result;
};

export const getOriginalFunctions = (ayanami) => {
