在v-treeview中删除项目的最好方法？

data() {
  return {
    treeData: [
      {
        label: '节点1',
        children: [
          {
            label: '子节点1'
          },
          {
            label: '子节点2'
          }
        ]
      },
      {
        label: '节点2'
      }
    ]
  }
}

<v-treeview v-model="treeData"></v-treeview>

methods: {
  deleteItem() {
    const node1 = this.treeData.find(node => node.label === '节点1');
    const index = node1.children.findIndex(child => child.label === '子节点1');
    node1.children.splice(index, 1);
  }
}

<button @click="deleteItem">删除项目</button>
