如何在javascript中编写包含另一种类型的自定义对象数组的自定义对象到firestore？

<script src="https://www.gstatic.com/firebasejs/9.0.0/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.0.0/firebase-firestore.js"></script>

// 初始化Firebase应用
firebase.initializeApp(firebaseConfig);

// 获取Firestore实例
const firestore = firebase.firestore();

class Person {
  constructor(name, age, friends) {
    this.name = name;
    this.age = age;
    this.friends = friends;
  }
}

// 创建自定义对象数组
const friendsArray = [
  { name: "John", age: 25 },
  { name: "Jane", age: 28 },
  { name: "Bob", age: 30 }
];

// 创建自定义对象
const person = new Person("Alice", 22, friendsArray);

// 获取要写入的集合引用
const collectionRef = firestore.collection("people");

// 将自定义对象写入集合
collectionRef.add(person)
  .then((docRef) => {
    console.log("Document written with ID: ", docRef.id);
  })
  .catch((error) => {
    console.error("Error adding document: ", error);
  });
