pop method for arrays

The pop method removes the last element of an array, and returns it also.

Code:

<script type="text/javascript">
//<![CDATA[

myArray = new Array("one", "two", "three");

document.write("myArray before being popped:<br>");

for (i=0; i<myArray.length; i++)
{
  document.write("myArray[", i, "] : ", myArray[i], "<br>");
}

poppedElement = myArray.pop();

document.write("<br>", "poppedElement : ", poppedElement, "<br><br>");

document.write("myArray after being popped:<br>");

for (i=0; i<myArray.length; i++)
{
  document.write("myArray[", i, "] : ", myArray[i], "<br>");
}
//]]>
</script>
