 <script type ="text/javascript">


	       var reverse = 0; 
                 var n = prompt("Enter reverse numbers: "); 
		while (n != 0) { 
                reverse = reverse * 10;
		reverse = reverse + parseInt(n%10); 
		n = parseInt(n/10); } 
		document.write(" The reverse of the number: "+reverse);	


</script>
<body>

</body>
</html>

and here's what I've done so far

var reverse = 0;
		
			
		var n = prompt("Enter reverse numbers: "); 
		
do {
reverse = reverse * 10;
		reverse = reverse + parseInt(n%10); 
		n = parseInt(n/10); } 
		document.write(" The reverse of the number: "+reverse);

}while(n != 0);}


When I run this it output a blank. Don't know where I got mistake. 
Thanks to your help God bless

Solution 1

You cannot use mathematical operations on strings (parseInt(n%10)). You first need to convert the entire input string into an integer and then do the reverse operation. Alternatively you could just split the string into an array of characters and then reverse them.
