如何在Vuex getter中连接数组

// store.js
const store = new Vuex.Store({
  state: {
    items: ['item1', 'item2', 'item3']
  },
  getters: {
    connectedItems: state => {
      return state.items.reduce((prev, curr) => prev + curr, '');
    }
  }
});

// MyComponent.vue
export default {
  computed: {
    connectedItems() {
      return this.$store.getters.connectedItems;
    }
  }
}

<!-- MyComponent.vue -->
<template>
  <div>
    Connected Items: {{ connectedItems }}
  </div>
</template>
