class类构造函数

class类构造函数

    class Hero{
        constructor(aname,atype,aword){
            this.aname = aname
            this.atype = atype
            this.aword = aword
        }
        sayWord(){
            alert(`${this.aname}说${this.aword}`)
        }
    }

    //细化类：extends 创建子类  super调用父类的方法【作为对象】
    class Fuzhu extends Hero{
        constructor(aname,atype,aword,www){
            super(aname,atype,aword)//使用this之前子类要调用super【作为方法使用】
            this.www = www
        }
        sayWord(){
            super.sayWord()
            alert(`游走`)
        }
    } 
    let yao = new Fuzhu('瑶','辅助','小鹿女啊，一定是世界上最不可爱的孩子吧','游走')
    console.log(yao)
    yao.sayWord()
