js_newuserdata(J, tag, ptr) creates a userdata object, wrapping the ptr. It takes the prototype for the new object from the top of the stack, just like js_newcconstructor does. js_touserdata(J, tag, idx) extracts the userdata pointer. Throws a TypeError if the object is not a userdata object with a matching tag. js_isuserdata(J, tag, idx) checks if a value on the stack is a userdata object with a matching tag.
