> I read Backbone's documentation and to me is a mess of heavy JS programming to achieve something that I don't know what it is.

That got me thinking.. Could I ever explain a non-web developer what Backbone is in a succinct way? I'm gonna try..

Web development is basically storing data at the server side, modifying and handling that data on both the server side and the client side. So basically you got multiple representations of the very same thing on two very different mediums. Passing and modifying that representation back and forth between those two very different mediums can be very tricky and error prone by itself, let alone the situation that you're handling varying numbers and varying types of these representations. Now what these MVC frameworks give us are idiomatic methods and structures attacking this very problem of representational hell.
