JavaScript Functions and OOP with prototype examples

JavaScript Funcitons

/** Module **/
var MyModule = (function() {
	var DEFAULT = {
		param: 'Hello World'
	}
	return {
		name: 'Israel Morales!',
		say: 'Because YOLO!',
		speak: function() {
			console.log('Hello World');
			return this; // Like jQuery chaining...
		},
		greet: function() {
			console.log(this.say);
			return this;
		},
		hello: function() {
			console.log(this.say +' '+ this.name);
			return this;
		},
		helloparams: function() {
			//var myArguments = arguments[0] || '';//default param if not provided
			var myArguments = arguments[0] || DEFAULT;
			console.log(myArguments.param);
		}
	}
})();

//MyModule.helloparams({ param: 'Aloha!'});
//MyModule.helloparams();

//Passing two objects
//MyModule.changeName({ name: 'Israel', lastname: 'Juan'},{name:'Jonathan', lastname: 'Ive'})

/** Scope chain **/
function test() {
	var name = 'Israel';
	var test2 = function() {
		//var name = 'Jorge';
		console.log(name);
	}
	test2();
};
//test();
/** Functions inside object **/
var Isra = {
	name: 'Israel',
	edad: 31,
	position: 'Web Developer',
	sayName: function() {
		console.log(this.name);
	}
}
//console.dir(Isra);
/** Object oriented approach **/
var Person = function() {
	var name;
	var age;
	var position;
	this.name = "Anonimo";
	this.age = 29;
	this.position = "Cashier";
	
}
var yell = function() {
	return 'Arrrghhh!!!';
}
var sayName = function() {
	return 'My name is: ' + this.name;
}
var presentYourself = function() {
	return 'My names is ' + this.name +' and my position is: '+ this.position;
}
Person.prototype.yell = yell;
Person.prototype.sayName = sayName;
Person.prototype.aboutMe = presentYourself;
var Persona1 = new Person;
Persona1.name = "Israel";
Persona1.age = 31;
Persona1.position = "Web Developer";
//console.dir(Persona1);
var Persona2 = new Person;
Persona2.name = 'Priscila Ramos';
//console.dir(Persona2);
