Note that private Names let you finally get a prototypal method that accesses instance-private data; you create the private Name inside an IIFE along with the constructor and the prototype methods, and use it to access data. Outside the IIFE no one can get to it. (WeakMaps provide the same ability through slightly different functionality, as Rick points out.) ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
