title: Freeing JavaScript object
body: <p>I am looking at the example from <a href="http://www.javascriptkit.com/javatutors/oopjs.shtml">http://www.javascriptkit.com/javatutors/oopjs.shtml</a></p>
  
  <pre><code>var person = new Object()
  person.name = "Tim Scarfe"
  person.height = "6Ft"
  </code></pre>
  
  <p>But there is no mention how to "free" it in order to avoid memory leak.</p>
  
  <p>Will the following code free it?</p>
  
  <pre><code>person = null;
  </code></pre>
  
  <ol>
  <li>How do you free a JavaScript Object using "new Object()? </li>
  <li>How do you free a JavaScript Array allocated using "new Array(10)"?</li>
  <li>How do you free a JavaScript JSON allocated using "var json = {"width": 480, "height": 640}"?</li>
  </ol>
  
  <p>Thanks in advance for your help.</p>
