help mixing in or inheriting from a base prototype using EventEmitter

[Gallagher Polyn]

Hi,

Given this...

function App(config) {

  EventEmitter.call(this);

  this.config = config;

}

App.prototype = Object.create(EventEmitter.prototype);

App.prototype.whatever = function() {

  // whatever

};

How can I mixin or inherit from App, say in Bapp...

function Bapp() {

  // ???

}

...such that instances of Bapp enjoy full use of App's methods, for example, "whatever()"? My efforts so far, have caused conflict with unimplemented EventEmitter methods on Bapp.

Thanks,

G
