How do I use the method prependChild?

The method prepend child takes one argument, the value to prepend,
inserts that value as the first child of the XML object and returns the
XML object.
Note that when the value passed in is an XMLList then each element in
the list is prepended.
Here are some examples:
  var gods = <gods>
    <god>Xibo</god>
  </gods>;
  gods.prependChild(<god>Kibo</god>);
  alert(gods);
  /* shows
  '<gods>
     <god>Kibo</god>
     <god>Xibo</god>
   </gods>'
  */
  // string value passed in prepended as text node:
  gods.prependChild("Kibology for all.");
  alert(gods);
  /* shows
  '<gods>
     Kibology for all.
     <god>Kibo</god>
     <god>Xibo</god>
   </gods>'
  */
  // XMLList value passed in prepends each element in the list:
  gods.prependChild(<><god>Maho</god><god>Jaffo</god></>);
  alert(gods);
  /* shows
  '<gods>
     <god>Maho</god>
     <god>Jaffo</god>
     Kibology for all.
     <god>Kibo</god>
     <god>Xibo</god>
   </gods>'
