Definition and Usage
The pop() method is used to remove and return the last element of an array.
Syntax
Tips and Notes
Note: This method changes the length of the array.
Tip: To remove and return the first element of an array, use the
shift() method.
Example
In this example we will create an array, and then remove the last element of
the array. Note that this will also change the length of the array:
<script type="text/javascript">
var arr = new Array(3);
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
document.write(arr + "<br />");
document.write(arr.pop() + "<br />");
document.write(arr);
</script>
|
The output of the code above will be:
Jani,Hege,Stale
Stale
Jani,Hege
