    constructor({

    } = {}) {
        super();
        this.count = count;
    }

    reduce(payload) {
        // when can handle payload, should return new state
        switch (payload.type) {
            case IncrementUseCase.Events.increment:
                return new ExampleState(Object.assign({}, this, {
                    count: this.count + 1
                }));
            case DecrementUseCase.Events.decrement:
                return new ExampleState(Object.assign({}, this, {
                    count: this.count - 1
                }));
            default: // when other payload, should return same state
                return this;
        }
    }
}

ReduceStore:

// LICENSE : MIT
"use strict";
import {ReduceStore} from "almin-reduce-store";
import ExampleState from "./ExampleState";
export default class ExampleStore extends ReduceStore {
    constructor() {
        super();
        this.state = new ExampleState();
    }

    getState() {
        return {
            example: this.state
        };
