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

Here is another way...

var reversed = num.toString().split('').reverse().join('');

jsFiddle.

If you wanted it again as a Number, use parseInt(reversed, 10). Keep in mind though, leading 0s are not significant in a decimal number, and you will lose them if you convert to Number.
