I'm creating a bare bones backbone example to try to learn it and am having issues getting my view to render. I've based it on Thomas Davis's tutorial but looked at many of the other apps and tutorials available.
I'm changing Davis's tutorial not only because I want to add an input box, but also because based on the backbone docs I thought it needed less code and a different structure. Obviously because I can't get this to work, I don't know what's needed and what isn't.
My ultimate goal was to just add the names in li tags within ul#friends-list, although I don't think el: 'body' will help me there.
What am I doing wrong? Thanks for any help.

Backbone.js Is Friendlyjs is neither difficult to learn nor difficult to use, and the time you will spend learning to use this serviceable framework will be well worth it, for you will learn how to use one of the most popular front-end frameworks and learn how to build modern web applications on the front end.
Backbone. Backbone has been around for a long time, but it's still under steady and regular development. It's a good choice if you want a flexible JavaScript framework with a simple model for representing data and getting it into views.
Front-End MVC frameworks (Backbone, Angular, etc) all rely on a backend service to provide the data that, say Backbone, would then use as its model. You could have an entire MVC pattern on the backend that accepts requests and spits out some JSON for a frontend MVC framework to use.
You had some fundamental problems with your code to get the functionality that you required. I turned your code into a jsfiddle and you can see the working solution here.

It might be easier if you use a collection like in the example instead.
Also I have just launched a new site containing Backbone tutorials which might help solve your problem.
