如何将类转换为简单的箭头函数

// 类的定义
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.`);
  }
}

// 转换为箭头函数
const createPerson = (name, age) => {
  const person = {
    name,
    age,
    sayHello: () => {
      console.log(`Hello, my name is ${name}. I'm ${age} years old.`);
    }
  };
  return person;
};

// 使用箭头函数创建对象
const john = createPerson('John', 25);
john.sayHello(); // 输出：Hello, my name is John. I'm 25 years old.
