下面是一個繼承的例子：

var cls = {};

?? ??? ?(function() {
?? ??? ??? ?function Map() {
?? ??? ??? ??? ?var than = this;
?? ??? ??? ??? ?this.Container_constructor(); //相當于as3 this.super();
?? ??? ??? ??? ?this.name = "開心";
?? ??? ??? ??? ?this.changeName = () => {
?? ??? ??? ??? ??? ?than.name = "sunny"
?? ??? ??? ??? ?}
?? ??? ??? ?}
?? ??? ??? ?var p = createjs.extend(Map, createjs.Container); //createjs.Container? 相當于 一般as3繼承Sprite
?? ??? ??? ?cls.Map = createjs.promote(Map, "Container");
?? ??? ?}());

?? ??? ?(function() {
?? ??? ??? ?function ChinaMap() {
?? ??? ??? ??? ?var than = this;
?? ??? ??? ??? ?this.Map_constructor();
?? ??? ??? ??? ?this.from = "北京";
?? ??? ??? ??? ?this.changeName = () => {
?? ??? ??? ??? ??? ?than.from = "sunny2"
?? ??? ??? ??? ?}
?? ??? ??? ?}
?? ??? ??? ?var p = createjs.extend(ChinaMap, cls.Map);
?? ??? ??? ?cls.ChinaMap = createjs.promote(ChinaMap, "Map");
?? ??? ?}());
?? ??? ?var chinaMap = new cls.ChinaMap();?? ??? ?
?? ??? ?console.log(chinaMap.name, chinaMap.from);//開心 北京
?? ??? ?chinaMap.changeName();
?? ??? ?console.log(chinaMap.name, chinaMap.from);//sunny2 北京
