I am not going to write something that on MVC that we learn in and out but I will point out some new look to it. Few days ago, I used to see a diagram in office where I was seating down something like this.

I just see some lightweight Model, View, and Controller in java script. Normally we do some MVC for server side some way it look like this.

But in first above diagram it has second MVC. I have work in some local storage and offline email system in HTML5 some months ago. How would it look like if we added HTML5 for this.

It will be full HTML5 web. This will give more capabilities for in actions in HTML5 such offline running, local storages and with it this will boost the speed.
