title: Fastest way to find the body tag via jQuery
body: <p>On every document ready I need to get the body tag via jQuery and I'm more curious about the answer to this than anything else.</p>
  
  <p>Let's say this is the body tag on every page on my site:</p>
  
  <pre><code>&lt;body id="body"&gt;
  </code></pre>
  
  <p>Is it faster to query the body tag by just the tag name:</p>
  
  <pre><code>$('body')
  </code></pre>
  
  <p>or query it by its id:</p>
  
  <pre><code>$('#body')
  </code></pre>
