Revealing Module Pattern, with internal prototype / constructor pattern

gistfile1.js

var myModule = ( function($, undefined) {
	var _person = function(firstName, lastName, age) {
		this.firstName = firstName;
		this.lastName = lastName;
		this.age = age;
	};

	_person.prototype.fullName = function() {
		return this.firstName + ' ' + this.lastName;
	};

	var myModule = {
		Person: _person,
	};
	return myModule;
})(jQuery);

// usage of instances
var newPerson = new myModule.Person('George', 'Costanza', 65);
var newPerson2 = new myModule.Person('Jerry', 'Seinfeld', 67);

newPerson.fullName(); // "George Costanza"
