如何使用key从多维数组中检索深子数组？

function searchDeepArray(arr, key) {
  for (let i = 0; i < arr.length; i++) {
    const element = arr[i];
    
    if (Array.isArray(element)) {
      const result = searchDeepArray(element, key);
      if (result) {
        return result;
      }
    } else if (typeof element === 'object' && element.hasOwnProperty(key)) {
      return element[key];
    }
  }
  
  return null; // 如果没有找到匹配的子数组，返回null或其他适当的值
}

// 示例用法
const multiDimensionalArray = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35, hobbies: ['reading', 'painting', 'music'] },
  { name: 'Dave', age: 40 }
];

const result = searchDeepArray(multiDimensionalArray, 'hobbies');
console.log(result); // 输出：['reading', 'painting', 'music']
