Vue在列表调用函数中生成最后一项

<template>
  <div>
    <ul>
      <li v-for="(item, index) in items" :key="index">
        {{ item }}
        <span v-if="isLastItem(index)">Last item</span>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      items: ['Item 1', 'Item 2', 'Item 3'],
    };
  },
  methods: {
    isLastItem(index) {
      return index === this.items.length - 1;
    },
  },
};
</script>
