如何查找嵌套在数组中的对象键的差异

function findKeyDifference(obj1, obj2) {
  // 检查obj1和obj2的类型，如果不是对象或数组，直接返回
  if (typeof obj1 !== 'object' || typeof obj2 !== 'object' || Array.isArray(obj1) || Array.isArray(obj2)) {
    return [];
  }

  let diffKeys = [];

  for (let key in obj1) {
    // 检查obj1中的键是否存在于obj2中
    if (!(key in obj2)) {
      diffKeys.push(key);
    } else {
      // 如果键存在于obj2中，递归比较它们的值
      const keyDiff = findKeyDifference(obj1[key], obj2[key]);

      // 如果存在差异，将差异的键添加到diffKeys数组中
      if (keyDiff.length > 0) {
        diffKeys.push(...keyDiff.map(subKey => key + '.' + subKey));
      }
    }
  }

  for (let key in obj2) {
    // 检查obj2中的键是否存在于obj1中
    if (!(key in obj1)) {
      diffKeys.push(key);
    }
  }

  return diffKeys;
}

const obj1 = {
  a: {
    b: 1,
    c: {
      d: 2,
      e: 3
    }
  },
  f: 4
};

const obj2 = {
  a: {
    b: 1,
    c: {
      d: 2,
      e: 5
    }
  },
  g: 6
};

const diffKeys = findKeyDifference(obj1, obj2);
console.log(diffKeys); // 输出 ['a.c.e', 'f', 'g']
