如何计算一个多维数组的值属于某个键？

function findValueByKey(array, key) {
  for (let i = 0; i < array.length; i++) {
    const element = array[i];
    if (typeof element === 'object') {
      const result = findValueByKey(element, key);
      if (result !== null) {
        return result;
      }
    } else if (Array.isArray(element)) {
      const result = findValueByKey(element, key);
      if (result !== null) {
        return result;
      }
    } else {
      if (element === key) {
        return element;
      }
    }
  }
  return null;
}

// 示例用法
const data = [
  {
    name: 'Alice',
    age: 25,
    hobbies: ['reading', 'painting'],
    address: {
      city: 'New York',
      country: 'USA'
    }
  },
  {
    name: 'Bob',
    age: 30,
    hobbies: ['coding', 'gaming'],
    address: {
      city: 'London',
      country: 'UK'
    }
  }
];

const result = findValueByKey(data, 'UK');
console.log(result); // 输出 'UK'
