根据父数组vue的id显示子数组吗？

<!-- 父组件 -->
<template>
  <div>
    <div v-for="item in parentArray" :key="item.id">
      <h2>{{ item.id }}</h2>
      <child-component :childArray="getChildArray(item.id)"></child-component>
    </div>
  </div>
</template>

<script>
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent
  },
  data() {
    return {
      parentArray: [
        { id: 1, children: ['child1', 'child2', 'child3'] },
        { id: 2, children: ['child4', 'child5'] },
        { id: 3, children: ['child6'] }
      ]
    };
  },
  methods: {
    getChildArray(id) {
      return this.parentArray.find(item => item.id === id).children;
    }
  }
};
</script>

<!-- 子组件 -->
<template>
  <div>
    <ul>
      <li v-for="child in childArray" :key="child">{{ child }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  props: ['childArray']
};
</script>
