在javascript中将普通对象转换为函数实例("类")

// 定义一个普通对象
const person = {
  name: 'John',
  age: 30,
  greet() {
    console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
  }
};

// 将普通对象转换为函数实例（类）
function Person(name, age) {
  this.name = name;
  this.age = age;
}

Person.prototype.greet = function() {
  console.log(`Hello, my name is ${this.name} and I am ${this.age} years old.`);
};

// 使用新创建的类实例化对象
const person1 = new Person('John', 30);
const person2 = new Person('Jane', 25);

// 调用类方法
person1.greet(); // 输出：Hello, my name is John and I am 30 years old.
person2.greet(); // 输出：Hello, my name is Jane and I am 25 years old.
