<h2>What is Backbone.js?</h2>

<blockquote cite="https://twitter.com/thegdb/status/148293778019581952">
Backbone.js gives structure to web applications by providing <em>models</em> with key-value binding and custom events, <em>collections</em> with a rich API of enumerable functions, <em>views</em> with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.

# 1. Organization
Backbone does not outline how to organize code
No directory structure or strict naming conventions
<br/>
### Again, many options
</section>
<section data-markdown>
## Modules are not new
<br />
<pre class="thin"><code contenteditable>function Module () {
return {
someStuff: { ... },
foo: function() { ... }
};
}
</code></pre>

Addy Osmani has helpful notes on the [Module pattern](http://addyosmani.com/resources/essentialjsdesignpatterns/book/#modulepatternjavascript).

# App Structure

### *Dependency management nightmare*

## How about a
## *module per file*?

<section data-markdown>
## Option 1
### Type Directory + Object File
<br />
<pre><code contenteditable>var UserModel = require('Models/User');
var UserView = require('Views/User');
</code></pre>
Which results in this file structure
<pre class="thin"><code contenteditable>|+ App
|+ Models
|- User.js
|+ Views
|- User.js
</code></pre>
</section>
<section data-markdown>
## Option 2
### Combo
<br />
<pre><code contenteditable>var UserModel = require('UserModel');
var UserView = require('UserView');
</code></pre>
Which results in this file structure
<pre class="thin"><code contenteditable>|+ App
|- UserModel.js
|- UserView.js
</code></pre>
</section>
<section data-markdown>
## Option 3
### Module Directory + Type File
<br />
<pre><code contenteditable>var UserModel = require('User/Model');
var UserView = require('User/View');
</code></pre>
Which results in this file structure
<pre class="thin"><code contenteditable>|+ App

|- View.js
