points:
(1) The abstraction will lose its effect;
(2) A second code generator must be maintained;
(3) It would be very difficult to maintain compatibility with older versions.
Through its advantages and shortcomings of the analysis found that they are so bright, so the choice of this Protocol as a transport layer on the protocol type needs to be considered more carefully, the advantage is the sacrifice of abstraction, easy maintenance and forward
name "Jsclass", but the method that relies on manual type to ensure correctness is not ideal.
So we're going to do this from the class definition itself, because objects in JavaScript (object) implement the ToString () method by default, and the ToString () Method of function objects (functions) is to return the definition itself of the function. This allows us to get the class name by handling the
