{
   var arr = ["orange", "mango", "banana", "sugar", "tea"];

   var removed_item = arr.splice(2, 0,"pineapple");
   document.write("After adding 1: " + arr );
   document.write("<br />removed_item is: " + removed_item);

   removed_item = arr.splice(3, 1);
   document.write("<br />After adding 1: " + arr);
   document.write("<br />removed_item is: " + removed_item);
}

</script>

Output will be:-

removed_item is:
