No easing functions in JSB (up to 3.15)

Hello guys!

I’m using cocos2d-js since version 3.9 and all the time I don’t find easings (cc.easeExponentialOut() for example) in JSB, for html5 everything works fine.
Maybe I am missing something? When porting my projects to android/iOS I always have to implement those easing functions by myself.
