As the pop() method removes and returns the last element, the shift() method removes and returns the first element of an array object. Since the first element is removed and returned this also affects the length of the array.

<script type="text/javascript">
         var rose =["Welcome","to","roseindia","Technologies"];
         document.write(rose.shift() + "<br />");
         document.write(rose.shift() + "<br />");
         document.write(rose);
      </script>
