trim() - FUNCTION

trim() Function

The trim() Function is used to remove any unwanted character from the String with Space by default.

<html>
<body>  
<script>

	var x = "   Hello  "
	var y = x.trim()
	document.write(y)
    
</script>      
</body>
</html>

Hello

In the above code, we have declared a String Hello with leading and trailing spaces.

var x = "   Hello  "

Then we have used the trim() function to remove any unwanted spaces from beginning and end.

var y = x.trim()

Unwanted spaces are stripped out of it.
