toUpperCase() - FUNCTION

toUpperCase() Function

The toUpperCase() Function is used to convert all the characters/letters of the String in upper case.

Example :

<html>
<body>  
<script>

	var x = "HeLLo"
	var y = x.toUpperCase()
	document.write("The String in upper case is ",y)
    
</script>      
</body>
</html>

Output :

The String in upper case is HELLO

In the above code, we have declared a String HeLLo, in which the letters e and o are in lower case.

x = "HeLLo"

So, we have used the toUpperCase() Function to convert them to upper case and assign to a variable y.

y = x.toUpperCase()
