title: Should "parent" not be used as javascript variable name (reserved words)
body: <p>I've often used the word "parent" as a JavaScript variable name, and have never had any problems.</p>
  
  <p>I've recently learned that "parent" can refer to something else such as when used to access an element in an IFrame's parent such as <code>parent.document.getElementById("someID")</code>.</p>
  
  <p>Should I stop using the word "parent" as a JavaScript variable name, and go through all my existing script to change it?
