如果你想知道一个物体是否属于某种类型，我相信你可以这样问：

person = {
     id: 1,
     name: 'John',
     age: 46,
     active: true
  };

  house = {
     color: 'blue with white patterns',
     years: 20,
     isInGoodCondition: true
  };

  const myArray = [person, house];

  myArray.forEach((element) => {
     if (element?.name) console.log('It is a person object');
     if (element?.isInGoodCondition) console.log('It is a house object');
  });

这个 object?.property 安全地问是否 property 存在于对象内部。
