In this article, you get a gentle introduction to the world of responsive web design, and learn how to create a simple responsive website layout.

As you start to use JavaScript to build larger and larger web apps with complex data structures and rich user interfaces, it becomes clear that the JavaScript language alone is not really up to the task.

In this article, Matt Doyle focuses on five fairly recent libraries and technologies that are starting to gain traction: Backbone, Underscore, Knockout, Sugar, and CoffeeScript.

Enjoy!
