Pop() to remove last element of an array

We can remove the last element of the array by applying pop() method to the JavaScript function. This way the array length or size also decreases by one. Here is the syntax of applying pop() method to an array

scripts.pop();

Where scripts is our array object.

We can use shift() object to remove first object from the array

Here is the complete code for example of pop() 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 pop()--<br>");
scripts.pop();
document.write(scripts.join(" <br> "));

</script>

The last element HTML will be removed from the array.
