title: Difference between Backbone.js and Jquery
body: <p>I'm just getting started with backbone, based on what I read, I couldn't tell the difference.
  Here is a description from backbone's website</p>
  
  <blockquote>
    <p>Backbone supplies structure to JavaScript-heavy applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing application over a RESTful JSON interface.</p>
  </blockquote>
  
  <p>Doesn't jQuery do event binding, etc nicely already?</p>
  
  <p>What purpose does backbone serves?</p>
