The Javascript Splice() method is used to add or remove any items to or from an array,and returns the removed item(s). This method changes the original array.
Javascript array splice() method changes the content of an array,adding new elements while removing old elements.

we can understand it by an example:-

<script type="text/javascript">

function splice_example()
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);


Output will be:-

After adding 1: orange,mango,pineapple,banana,sugar,tea
removed_item is:
After adding 1: orange,mango,pineapple,sugar,tea
removed_item is: banana
