In general when ever we talk about MVC we think about software engineering and design patterns which ease the life for a software developers. But MVC is not only a a design pattern for software engineering,  MVC is also a recommended pattern for HCI/Usability suggested by Jan Borchers in his book “A Pattern Approach to Interaction Design” .

Why we need it?

In today’s world of software development usability and interaction design considerations are inevitable. We all know about the buzz “Enterprise 2.0” ( I will be posting some of my ideas on this very soon) and we just not think of an enterprise application without lots of big and really long forms. As web has become a ‘de facto’ standard for new breed of software’s in anyway we need to put a lot of client side validations(a hefty line of codes) and usability and UI tweaking for web forms.

Yes I can understand, no body wants to be remembered of those nightmares, but it is inevitable in any way. So please consider using a MVC here even for this forces of software designing.

We have ‘views’ as forms, we have ‘models’ and business/validation logic  and if we could glue-in the ‘controller’ we are done to solve our puzzle by using MVC in javascripts.

Going more into the frameworks available as of today is out of the scope of this article but I would like to put more in this subject when ever I get some more time to provide my readers a working samples to use and evaluate. For the time being the list of best(according to me) javascript MVC frameworks available for use.
