Regarding Retrieving Platform Specific Data using cocos2d-JS

I need to take some data from the device , so wanted some guidelines on how should I got about it with cocos2d-JS 3.x .
In cocos2d-x , we can do JNI Calls and then retrieve it in the main class but since cocos2d-x JS has jsb bindings & plugin-x architecture I am little bit confused how to start because there are core modules for specific thing share,social and IAP etc… I am not sure if there is any module to retrieve platform specific data.

Thanks for your time it would be great help If you can guide me through it

I suggest you to use the reflection feature : http://cocos2d-x.org/docs/manual/framework/html5/v3/reflection/en
