My favorite JS pattern

I think this is not the most faster pattern, but this the most readable and understandable to me.

The following code is self explanatory. I commented it line to line.

To watch this code working, follow http://jsfiddle.net/DknAX/1/ and observe your 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);
