2.10类的定义与继承

// 如何定义一个类，如何在类里面定义属性和方法
class Person2 {
  name = "dell";
  getName() {
    return this.name;
  }
}
// Perso2是父类，Teacher2是子类
class Teacher2 extends Person2 {
  getTeacherName() {
    return "dell";
  }
  getName() {
    return super.getName() + "lee";
  }
}
const person = new Person2();
console.log(person.getName());

const teacher2 = new Teacher2();
console.log(teacher2.getTeacherName());
