jQuery is a feature-rich JavaScript library that makes HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a variety of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery solves the problems of DOM manipulation, event detection, AJAX calls, element selection and document queries, element attribute and data management, as well as object management utilities.

The key concept of the Factory pattern is to abstract the way an object or a group of related objects are created and initialized for a specific purpose. The point of this abstraction is to avoid coupling an implementation with specific classes or the way that each object instance needs to be created and configured. The result is an implementation that works as an abstract way for object creation and initialization...
