类的定义

1. 简单类的定义

class Person{
    public eye='两只眼睛'
    constructor(name,age,color){
        this.name = name;
        this.age = age;
        this.color = color;
        this.xxx = eye;
    }
    sleep(){
        return '正在睡觉..'
    }
    eat(){
        return '正在吃饭'
    }
    //静态方法
    static war(){
        return '开始发动战争....'
    }
}

let p1 = new Person('张麻子',40,'黄皮肤')

class Person{
    //定义类属性的类型
  public name:string
  public age:number
  public color:string

  constructor(name:string,age:number,color:string){
      this.name = name;
      this.age = age;
      this.color = color;
  }
  sleep():string{
      return '正在睡觉..'
  }
  eat():string{
      return '正在吃饭'
  }
}

let p1 = new Person('张麻子',40,'黄皮肤')
console.log(p1);
console.log(  p1.eat() );
