unShift method for arrays

The unShift method adds an element to the start of an array.

Code:

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

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

document.write("myArray before the unShift method is applied:<br>");
for (i=0; i<myArray.length; i++)
{
  document.write("myArray[", i, "] : ", myArray[i], "<br>");
}

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

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

//]]>
</script>
