Example JavaScript Pseudo-class

gistfile1.js

// Example Pseudo-class
var Animal = (function() {
	
	function Animal(name) {
		this.name = name;
	}
	
	Animal.prototype.getName = function () {
		return this.name;
	};
	
	return Animal;
}());

var dog = new Animal('Fido');
console.log(dog.getName());

If you like OOP Classes then this might be useful. A module encapsulates the class members and returns the constructor.
