如何从两个对象中获取新的JavaScript对象，该对象具有键值和键值匹配时的平均值

function getAverageObject(obj1, obj2) {
  const result = {};

  for (const key in obj1) {
    if (obj2.hasOwnProperty(key)) {
      const average = (obj1[key] + obj2[key]) / 2;
      result[key] = average;
    }
  }

  return result;
}

// 示例用法
const obj1 = { a: 1, b: 2, c: 3 };
const obj2 = { a: 4, b: 5, d: 6 };
const averageObj = getAverageObject(obj1, obj2);
console.log(averageObj);

{ a: 2.5, b: 3.5 }
