如何克隆Vuex阵列？

// store.js
import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex);

const store = new Vuex.Store({
  state: {
    myArray: [1, 2, 3, 4, 5]
  },
  mutations: {
    // 定义一个mutation用于修改数组
    updateArray(state, newArray) {
      state.myArray = newArray;
    }
  },
  actions: {
    // 定义一个action用于触发mutation
    cloneArray({ commit, state }) {
      const clonedArray = [...state.myArray]; // 使用ES6的扩展运算符克隆数组
      commit('updateArray', clonedArray);
    }
  }
});

export default store;

// MyComponent.vue
<template>
  <div>
    <button @click="cloneArray">克隆数组</button>
    <ul>
      <li v-for="item in myArray" :key="item">{{ item }}</li>
    </ul>
  </div>
</template>

<script>
import { mapActions } from 'vuex';

export default {
  methods: {
    ...mapActions(['cloneArray'])
  },
  computed: {
    myArray() {
      return this.$store.state.myArray;
    }
  }
};
</script>
