Meu padrão JS favorito

Acho que este não é o padrão mais rápido, mas é o mais legível e compreensível para mim.

O código a seguir é autoexplicativo. Eu comentei linha a linha.

Para ver este código funcionando, siga http://jsfiddle.net/DknAX/1/ e observe seu console.

// All functions have now the compose method
Function.prototype.compose  = function(argFunction) {
    var invokingFunction = this;
    return function() {
        return  invokingFunction.call(this,argFunction.apply(this,arguments));
    }
}

// For things who work as an electronic
var asEletronic = function() {
    // Exclusive eletronic property
    this.on = false;
    // Exclusive eletronic property
    this.voltage = 110;
    // Exclusive eletronic method
    this.switchPower = function() {
        if(this.on === true) {
            this.on === false;
            console.info('Eletronic is OFF');
        } else {
            this.on === true;
            console.info('Eletronic is ON');
        }
    }
}

// For things who work as an sound reproducer
var asSoundReproducer = function() {
    // Exclusive sound reproducer property
    this.mp3Support = true;
    // Exclusive sound reproducer property
    this.volume = 10;
    // Exclusive sound reproducer method
    this.increaseVolume = function() {
        this.volume++;
        console.info('Volume increased to: ' + this.volume);
    }
    this.decreaseVolume = function() {
        this.volume--;
        console.info('Volume decreased to: ' + this.volume);
    }
}

var TV = function() {
    console.info('New TV instantiated');
    // Core TV property
    this.pol = 42;
    // Core TV property
    this.fullHD = true;
}

var MicroSystem = function() {
    console.info('New Micro System instantiated');
    // Core micro system property
    this.station = 102.9;
    // Core micro system method
    this.setStation = function(newStation) {
        this.station = newStation;
        console.info('Micro System are now in station ' + newStation);
    }
}


// Composing a TV
// TV works like a eletronic
TV = TV.compose(asEletronic);
// TV works like a sound reproducer
TV = TV.compose(asSoundReproducer);

// Composing a Micro System
// Micro system works like a eletronic
MicroSystem = MicroSystem.compose(asEletronic);
// Micro system works like a sound reproducer
MicroSystem = MicroSystem.compose(asSoundReproducer);


// A new TV instantiation
var myTV = new TV();

// Logging myTV to see what it have inside
console.log(myTV);


// A new Micro System instantiation
var myMicroSystem = new MicroSystem();

// Logging myMicroSystem to see what it have inside
console.log(myMicroSystem);


// Turn on my TV
myTV.switchPower();
// Increasing TV volume
myTV.increaseVolume();

// Turn on my Mycro System
myMicroSystem.switchPower();
// Logging current station
console.info('Current station: ' + myMicroSystem.station);
// Setting a new station
myMicroSystem.setStation(88.5);
// Logging current station
console.info('Current station: ' + myMicroSystem.station);
