作用:

可以将复杂的类进行一些拆分,让抽象和实现进行分离解耦,可以让每一个部分都可以单独维护

方便扩展和维护

示例:

        class Obj {
            constructor(person) {
                this.person = person
                this.name = person.name
            }
            getHobby(){
                return this.person.hobby
            }
            getBehavior(){
                return this.person.behavior()
            }
        }

        class Human {
            constructor(hobby) {
                this.name = '打工人'
                this.hobby = hobby
            }
            behavior() {
                console.log('一身打工人的怨气')
            }
        }
        class Deity {
            constructor(hobby) {
                this.name = '神仙'
                this.hobby = hobby
            }
            behavior() {
                console.log('过着神仙般的生活')
            }
        }

        const wjt = new Obj(new Human('抖音刷美女,或者打游戏'))
        const sunwukong = new Obj(new Deity('定身七仙女,然后吃桃子'))

        console.log(wjt.name+'的爱好:'+wjt.getHobby())
        console.log(sunwukong.name+'的爱好:'+sunwukong.getHobby())
