如何在Vue Js中循环Json数组中的子数组？

<template>
  <div>
    <div v-for="item in jsonArray" :key="item.id">
      <h2>{{ item.title }}</h2>
      <ul>
        <li v-for="subItem in item.subArray" :key="subItem.id">
          {{ subItem.name }}
        </li>
      </ul>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      jsonArray: [
        {
          id: 1,
          title: "Array 1",
          subArray: [
            { id: 1, name: "Sub Item 1" },
            { id: 2, name: "Sub Item 2" },
            { id: 3, name: "Sub Item 3" }
          ]
        },
        {
          id: 2,
          title: "Array 2",
          subArray: [
            { id: 4, name: "Sub Item 4" },
            { id: 5, name: "Sub Item 5" },
            { id: 6, name: "Sub Item 6" }
          ]
        }
      ]
    };
  }
};
</script>
