includes() - FUNCTION

includes() Function

The includes() Function is search for the substring and returns true if it is present and false if not.

Example :

<html>
<body>  
<script>

	var x = "Hello Beautiful World"
	var y = x.includes("Beautiful")
	if (y == true) {
		document.write("The substring Beautiful is present in the String")
	}
	else {
		document.write("The substring Beautiful is not present in the String")	
	}
    
</script>      
</body>
</html>

Output :

The substring Beautiful is present in the String

In the above code, we have declared a String Hello Beautiful World and assigned it to a variable x.

x = "Hello Beautiful World"

And we would be searching the substring Beautiful, from the String, Hello Beautiful World.

So, we have used the includes() Function to search the substring Beautiful.

y = x.includes("Beautiful")

And what includes() Function does is, goes to the String Hello Beautiful World and searches for the substring Beautiful.

And finds the substring Beautiful in the 6th position.

So it returns true.

And the if statement finds a match.

if (y == true) {
	document.write("The substring Beautiful is present in the String")
}
else {
	document.write("The substring Beautiful is not present in the String")
}
