JavaScript has been turning up everywhere. With nearly every desktop and mobile web browser on the planet coming equipped with a JavaScript engine, the language has become the de facto standard for client side code. There is just no better way to guarantee your audience can access the full feature set of your application.

Although JavaScript has typically been regarded as a client side technology, in-roads have been made in other areas in recent years. Frameworks like node.js are powering major server side applications and JavaScript can even be found querying some of the major NoSQL databases.

Update:  We've released a full JavaScript development guide: JavaScript Nuts and Bolts, and are teaching a class explaining how to use JavaScript, KendoUI and ASP.NET MVC in Telerik's Sitefinity CMS. Sign up for Foundations of Sitefinity 5.1.

JavaScript uses unfamiliar patterns to simulate object oriented programming. Well, unfamiliar to class-based languages such as C# and Java programmers that is. For example, JavaScript has no classes and uses functions/objects somewhat interchangeably ("it's a desert topping and a floor wax!").

In my previous post, I showed how to build a mobile web app using jQuery Mobile. Its use of HTML5 data attributes and CSS classes made it pretty straightforward, especially if you are used to building regular websites. The architecture of your mobile website would have to be based on the server-side though, whether this be ASP.NET MVC, PHP, Ruby, etc. Then I came across Sencha Touch which changes this mentality to a more progressive approach… client-side applications!
