如何求数组中object和included对象中所有值的和？

function sumValues(obj) {
  let sum = 0;
  for (let key in obj) {
    if (typeof obj[key] === 'number') {
      sum += obj[key];
    } else if (typeof obj[key] === 'object' && obj[key] !== null) {
      sum += sumValues(obj[key]);
    }
  }
  return sum;
}

function sumArrayObjects(arr) {
  let totalSum = 0;
  for (let item of arr) {
    if (typeof item === 'object' && item !== null) {
      totalSum += sumValues(item);
      if (item.included && Array.isArray(item.included)) {
        for (let includedItem of item.included) {
          totalSum += sumValues(includedItem);
        }
      }
    }
  }
  return totalSum;
}

// 示例数据
const data = [
  { a: 1, b: 2, included: [{ c: 3 }, { d: 4 }] },
  { e: 5, f: 6 },
  { g: 7, included: [{ h: 8 }] }
];

console.log(sumArrayObjects(data)); // 输出: 36
