title: jQuery best practice for $($(".elem")[0])?
body: <p>Is there a way to only use ONE dollar sign instead of doing this?</p>
  
  <pre><code>$($(".elem")[0]).hide()
  </code></pre>
  
  <p>I could use :first, but what about if I wanted the third or so:</p>
  
  <pre><code>$($(".elem")[2]).hide()
  </code></pre>
