过滤多级嵌套的对象数组，取回数组中匹配的对象

function filterNestedObjects(arr, condition) {
  let result = [];

  for (let obj of arr) {
    if (isObjectMatch(obj, condition)) {
      result.push(obj);
    }

    for (let key in obj) {
      if (Array.isArray(obj[key])) {
        let nestedResult = filterNestedObjects(obj[key], condition);
        result = result.concat(nestedResult);
      }
    }
  }

  return result;
}

function isObjectMatch(obj, condition) {
  for (let key in condition) {
    if (obj[key] !== condition[key]) {
      return false;
    }
  }
  return true;
}

// 示例用法
let data = [
  {
    id: 1,
    name: 'John',
    children: [
      {
        id: 2,
        name: 'Alice',
        children: [
          {
            id: 3,
            name: 'Bob',
            children: []
          }
        ]
      },
      {
        id: 4,
        name: 'Eve',
        children: []
      }
    ]
  },
  {
    id: 5,
    name: 'Mike',
    children: []
  }
];

let condition = {
  name: 'Bob'
};

let filteredData = filterNestedObjects(data, condition);
console.log(filteredData);
