简化代码还有空间吗?

Creator 2.x
#1

//代码片段一
cc.tween(this.node).repeatForever( cc.tween().sequence( cc.tween().delay(4), cc.tween().repeat( 2, cc.tween().sequence( cc.tween().to(0.2, { scaleX: 1.2, scaleY: 0.8 }), cc.tween().to(0.1, { scaleX: 1, scaleY: 1 } ) ) ) ) ).start()

//代码片段二
this.node.runAction( cc.sequence( cc.delayTime(4), cc.repeat( cc.sequence( cc.scaleTo(0.2, 1.2, 0.8), cc.scaleTo(0.1, 1) ), 2 ) ).repeatForever() );

#2

let delayTween = cc.tween().delay(4); let scaleTween = cc.tween().to(0.2, { scaleX: 1.2, scaleY: 0.8 }).to(0.1, { scaleX: 1, scaleY: 1 }); let repeatTween = cc.tween().repeat(2,scaleTween) let sequence_ForeverTween = cc.tween().sequence(delayTween,repeatTween); cc.tween(this.node).repeatForever(sequence_ForeverTween).start();
