Question about Cocos2dx and Facebook developers

Hy,
I have a question about Cocos2dx,
Im currently working on a game in C++ for iOS, i know that i can put my game on android too if i modify the graphics and some other aspects but my question in the following:
Can i also be a Facebook developer ? my C++ code based game will also work on Facebook as an facebook app?
Thank you in advance

C++ is used to make native executables. You can use cocos2d-html5 for browser based Facebook applications.
Using JavaScript binding while developing the native part will make easier porting your game to cocos2d-html5 I guess.
