使用非构造函数方法反序列化为类

// 定义一个类
class Person {
  constructor(name, age) {
    this.name = name;
    this.age = age;
  }
  
  sayHello() {
    console.log(`Hello, my name is ${this.name}. I'm ${this.age} years old.`);
  }
}

// 序列化一个Person对象
const serializedData = JSON.stringify({ name: 'Alice', age: 25 });

// 反序列化为Person类的实例
const deserializedObj = JSON.parse(serializedData);
Object.setPrototypeOf(deserializedObj, Person.prototype);
const person = Object.create(Person.prototype);
Object.assign(person, deserializedObj);

person.sayHello(); // 输出：Hello, my name is Alice. I'm 25 years old.
