我在react中使用mobx做狀態(tài)管理實(shí)現(xiàn)了簡單計(jì)數(shù)器demo，如果該頁面今后需要添加新的功能，我希望不同功能存放在不同的store,請問這要如何實(shí)現(xiàn)

countStore.js

import { observable,action, computed } from 'mobx';
class CountStore{
    @observable num = 0;
    @computed get displayResult(){
        return this.num;
    }
}

export default CountStore;

app.js

import React, { Component } from 'react';
import { render } from 'react-dom';
import Count from './count';
import Display from './display';
import CountStore from "../store/countStore";
const CountStores = new CountStore();
class Countapp extends Component{
    constructor(props){
        super(props)
    }

    render(){
        return <div>
            
            <Count store={CountStores}/>
            <Display store={CountStores}/>
            
        </div>
    }
}

export default Countapp;
