title: What's the difference between a jQuery object and a DOM element? Difference between .get() and .index()?
body: <p>I'm lead to this question when trying to figure out the difference between jQuery's <code>.get()</code> and <code>.index()</code>, I've looked over the jQuery API and I still don't get what the difference is between them, maybe i'm not understanding the terminology?</p>
  
  <p>What's the difference between a jQuery object and a DOM element? And are a DOM element and a DOM node the same thing? Are they just <code>&lt;div&gt;</code> and <code>&lt;a&gt;</code> etc. is a DOM node/DOM element just an HTML tag? </p>
  
  <p>EDIT: and isn't the DOM just the structure of the page? <code>&lt;html&gt;&lt;body&gt;etc.&lt;/body&gt;&lt;/html&gt;</code>?</p>
