        v-for指令：
            1.用于展示列表数据
            2.语法：v-for="(item,index) in arr" :key="item.id"
            3.可遍历：数组、对象、字符串
     -->
    <!-- 准备一个容器 -->
    <div id="root">
      <ul>
        <!-- 使用v-for遍历数组 -->
        <li v-for="(item,index) in persons" :key="item.id">
          {{item.id}}-----{{item.name}}------{{item.age}}岁-----{{item.sex}}
        </li>
      </ul>

      <div>汽车信息</div>
      <ul>
        <!-- 使用v-for遍历对象 -->
        <li v-for="(value,key) in car" :key="key">{{value}}</li>
