JavaScript array remove
In JavaScript array there is not any in-built method
that will remove the specified element according to the user's choice. So we can
use the pop() method to remove the element of the array. We can create different
methods that will remove the specified element by using the pop() method. Here
in the following example we have created a simple remove() method that
will remove an array element from the back end side.
In following example code we have created the function remove()
which accepts the Array Object name and performs the pop()
operation on the passed array object.
function remove(arrayName)
{
arrayName.pop();
document.writeln("==>Removed one element
by the end of Array</br>");
} |
Here is the sample code of JavaScript array remove
example as follows:

arr[3]="Pvt";
arr[4]="Ltd";
function remove(arrayName)
{
arrayName.pop();
document.writeln("==>Removed one element by the end of Array</br>");
}
document.writeln("Array before calling remove() method is =<b>"+arr+"</b></br>");
remove(arr);
document.writeln("Array after calling remove() method is =<b>"+arr+"</b></br>");
</script>
</head>
