title: Javascript: remove an element.cloneNode() from memory
body: <p>I am a situation where I have to clone an element, read it's attributes and other parsing functionality, but now since I don't do <code>element.parentNode.appendChild(clonedElement)</code> how do I delete this clone from memory?</p>
  
  <pre><code>var clonedElement = element.cloneNode();
  
  // do some stuff with it
  
  clonedElement = null; // is this good enough?
  </code></pre>
  
  <p>So yea, is the <code>clonedElement = null;</code> good enough to clear it from memory?</p>
