计算对象属性的总和并将其存储在数组中

function calculateObjectPropertySum(obj) {
  let sumArray = [];

  for (let key in obj) {
    if (typeof obj[key] === 'number') {
      let sum = 0;
      for (let innerKey in obj[key]) {
        sum += obj[key][innerKey];
      }
      sumArray.push(sum);
    }
  }

  return sumArray;
}

// 示例对象
let obj = {
  prop1: [1, 2, 3],
  prop2: [4, 5, 6],
  prop3: 'not a number',
  prop4: [7, 8, 9]
};

// 调用函数并输出结果
console.log(calculateObjectPropertySum(obj));
