Reverse decimal digits in javascript

Question

How do I reverse the digits of a number using bitwise?

input:

x = 123; 

output:

x = 321; 

Answer 1

you also use this function

function myfunction(a){
   var x=a.toString();
   var y= x.split("");
   var z=y.reverse();
   var result=z.join("");
     return result;

} myfunction(123);

Answer 2

The code block below should do the trick

<script type = "text/javascript">

var input;

input=window.prompt ("Please enter a number to be reversed.");
x=input.length;

while(x > 0)
{

x=x-1;
document.write(input[x]);

}

</script>
