The Janus Duktape plugin implements all the mandatory hooks to allow the C code to interact with a custom JavaScript script, and vice-versa. Anyway, JavaScript developers may want to have the C code do more than what is provided out of the box, e.g., by exposing additional JavaScript methods from C for further low level processing or native integration. This "extra" implementation provides a mechanism to do just that, as developers can just add their own custom hooks in the C extra code, and the Duktape plugin will register the new methods along the stock ones.

More specifically, the Janus Duktape plugin will always invoke the janus_duktape_register_extra_functions() method when initializing. This means that all developers will need to do to register a new function is adding new duk_push_c_function calls to register their own functions there, and they'll be added to the stack.
