shift() to remove last element of an array

To remove the last element from an array we have used php() method. Same way we can use shift() method to remove first element of an array in JavaScript. This also decreases length of an array. Here is the syntax of applying shift() method to an array

scripts.shift();

Where scripts is our array object.

Here is the complete code for example of shift() function.

<script type="text/javascript">
var scripts = new Array();
scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";
document.write(scripts.join(" <br> "));
document.write("<br>--Now after applying shift()--<br>");
scripts.shift();
document.write(scripts.join(" <br> "));

</script>

The last element HTML will be removed from the array.

We can remove elements from any position of an array by using splice method
