indexOf() - FUNCTION

The indexOf() Function is used to return the first occurrence of an element in the Array.

Let us say, we have a Array that contains three names, Mohan, Kriti and Salim. And we want to find the location of Kriti.

Example :

<html>
<body>  
<script>

	var x = ["Mohan", "Kriti", "Salim"]
	var y = x.indexOf("Kriti")
	document.write("The position of Kriti is ",y) 
    
</script>      
</body>
</html>

Output :

The position of Kriti is 1

So, in the above code we have created a Array and initialised to the variable x.

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

Below is how the values are positioned in the Array,

Now, if we see the above diagram, Kriti resides at position/index 1.

And the indexOf() Function is used to find the position of Kriti.

y = x.indexOf("Kriti")

And we get the below output,

The position of Kriti is 1
