splice() - FUNCTION

splice() Function is used to add or remove elements from an Array.

Let us say, we have a Array that contains four names, Mohan, Kriti, Philip and Salim. And we want to remove the elements Kriti and Philip from the Array.

Removing a chunk of elements from the Array using splice() function

Example :

<html>
<body>  
<script>

	var x = ["Mohan", "Kriti", "Philip", "Salim"]
	x.splice(1,2)
	document.write(x)
    
</script>      
</body>
</html>

Output :

Mohan,Salim

So, we have the below Array,

var x = ["Mohan", "Kriti", "Philip", "Salim"]

And we want to remove the elements Kriti and Philip from the Array.

x.splice(1,2)

Next, let us say, we have a Array that contains four names, Mohan, Kriti, Philip and Salim. And we want to add the name Benny in between Philip and Salim.

Adding elements to the Array at a specific location

Example :

<html>
<body>  
<script>

	var x = ["Mohan", "Kriti", "Philip", "Salim"]
	x.splice(3, 0, "Benny")
	document.write(x)
    
</script>      
</body>
</html>

Output :

Mohan,Kriti,Philip,Benny,Salim

So, all we have done is used the splice() method to add the name Benny at index 3. And also mentioned 0. So that no elements gets removed from the array.

x.splice(3, 0, "Benny")

And what happens is Benny gets inserted at index 3 pushing Salim at index 4.
