Assignment to better understand motivation of Backbone/frameworks

I got started with web development a few months ago. I had never gone through the struggles of spaghetti code with JS/jQuery.

Learning Backbone/other frameworks before going through this seems like learning the solution before understanding the problem. I know you talked about the problem a bit, but it doesn't seem like enough to me. Perhaps you could a) talk about it some more and/or b) give us an assignment that forces us to encounter the problems.
