为v-for中的每一项呈现异步的日期

<template>
  <div>
    <ul>
      <li v-for="item in items" :key="item.id">
        {{ item.name }} - {{ item.date }}
      </li>
    </ul>
  </div>
</template>

<script>

        { id: 2, name: 'Item 2', date: null },
        { id: 3, name: 'Item 3', date: null },
      ],
    };
  },
  mounted() {
    this.getItemsDate();
  },
  methods: {
    async getItemsDate() {
      // Simulating asynchronous date fetching using setTimeout
      await this.fetchDateForItem(1, 1000); // Fetch date for Item 1 after 1 second

    },

      return new Promise((resolve) => {
        setTimeout(() => {
          const item = this.items.find((item) => item.id === itemId);
          if (item) {
