slice() - FUNCTION

slice() Function

The slice() Function is used to extract a couple elements from the given Array.

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

Accessing a chunk of elements from the Array using slice() function using positive index

Example :

<html>
<body>  
<script>

	var x = ["Mohan", "Kriti", "Philip", "Salim"]
	var y = x.slice(1,3)
	document.write(y)
    
</script>      
</body>
</html>

Output :

Kriti,Philip

So, we have the below Array,

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

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

var y = x.slice(1,3)

Accessing a chunk of elements from the Array using slice() function using negative index

Example :

<html>
<body>  
<script>

	var x = ["Mohan", "Kriti", "Philip", "Salim"]
	var y = x.slice(-3,-1)
	document.write(y)
    
</script>      
</body>
</html>

Output :

Kriti,Philip
