如何过滤对象数组的子对象，然后返回具有更新的子对象的父对象？

// 假设有一个对象数组
const parentObjects = [
  {
    id: 1,
    name: "Parent 1",
    child: { id: 1, name: "Child 1" }
  },
  {
    id: 2,
    name: "Parent 2",
    child: { id: 2, name: "Child 2" }
  },
  {
    id: 3,
    name: "Parent 3",
    child: { id: 3, name: "Child 3" }
  }
];

// 过滤条件：子对象的id为2
const filterCondition = 2;

// 过滤并更新父对象的子对象
const filteredParents = parentObjects.map(parent => {
  if (parent.child.id === filterCondition) {
    // 更新子对象
    parent.child.name = "Updated Child";
  }
  return parent;
});

console.log(filteredParents);
