N-API Callback Return

I think N-API doesn't have any documented way for return something from callbacks. we have just napi_get_cb_info for reading information from napi_callback_info and there is no specific way for write something into them but in documentation mention that it can be used for Set the return value of the callback

The documentation is out of date. You can return a napi_value directly from a function callback. The current definition of napi_callback has a napi_value return type, not void:

typedef napi_value (*napi_callback)(napi_env env, napi_callback_info info);

Thank you very much @jasongin

I'll clarify this in a doc PR next week.
