Reverse decimal digits in javascript

Question

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

output:

x = 321; 

Answer 1

OK, how about using and chaining these popular tricks in JavaScript in one-line function as below...

const reverseNum = num => +("" + ~~num.split("").reverse().join(""));

And call it like these:

reverseNum(123); //321
reverseNum(423.09); //324
reverseNum(23305.1); //50332
reverseNum(89112); //21198
reverseNum(568434.2389); //434865
