What is meant by “public function can't be overridden if a patch is necessary.” in Addy's description of the Revealing Module Pattern?

Question

A disadvantage of this pattern is that if a private function refers to a public function, that public function can\'t be overridden if a patch is necessary. T

Answer 1

I would bind getName to this, which, it seems, points to the content returned in RMP.

function makeGreeter(name){
    this.getName = function(){ return name;};
    var _sayHello = function(){console.log("Hello, " + this.getName());};
    return {
            getName: getName,
            sayHello: _sayHello
    }
}

I prefer this, though:

function makeGreeter(name){
    this.getName = function(){ return name;};
    var _sayHello = function(){console.log("Hello, " + this.getName());};
    var API = {
        getName: getName,
        sayHello: _sayHello
    };
    return API;
}
