join() - FUNCTION

join() Function is used to join all the elements of the Array into a String.

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

Example :

<html>
<body>  
<script>

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

Output :

Mohan,Kriti,Philip,Salim

So, we have an Array that has 4 names.

So, all we have done is, used the join() method to convert the elements of the array into a string.

var y = x.join()

Next, let us say we want to convert the array elements into a String. But we don't want the names separated by comma ','.

Rather, we want the names separated by @.

Example :

<html>
<body>  
<script>

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

Output :

Mohan@Kriti@Philip@Salim

So, we have an Array that has 4 names.

So, all we have done is, used the join() method to convert the elements of the array into a string.

var y = x.join("@")
