shift method for arrays

The shift method removes the first element from an array, and also returns that element.

Code:

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

myArray = new Array("a","b","c","d","e");

document.write("myArray before the shift method is applied:<br>");

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

document.write("<br>");

returnedElement = myArray.shift();

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

document.write("myArray after the shift method is applied:<br>");

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

Output:
