Which pattern jQuery $.fn.extend or $.extend use
<p>I was just reading <a href="http://stackoverflow.com/questions/3790909/javascript-module-pattern-vs-constructor-prototype-pattern">Javascript: Module Pattern vs Constructor/Prototype pattern?</a> and I was curious to know that when we extend our class with $.fn.extend or $.extend which pattern is used, Module Pattern or Constructor/Prototype pattern?</p>
