从数组到对象并创建子类

// 从数组到对象
var studentArray = ["Alice", 18, "Female"];
var studentObject = {
  name: studentArray[0],
  age: studentArray[1],
  gender: studentArray[2]
};
console.log(studentObject); // 输出：{ name: "Alice", age: 18, gender: "Female" }

// 创建子类
class Person {
  constructor(name, age, gender) {
    this.name = name;
    this.age = age;
    this.gender = gender;
  }
  
  sayHello() {
    console.log("Hello, my name is " + this.name);
  }
}

class Student extends Person {
  constructor(name, age, gender, major) {
    super(name, age, gender);
    this.major = major;
  }
  
  study() {
    console.log("I am studying " + this.major);
  }
}

var student = new Student("Alice", 18, "Female", "Computer Science");
student.sayHello(); // 输出：Hello, my name is Alice
student.study(); // 输出：I am studying Computer Science
