Day 34: Reverse Number of Number of 100DaysCodingChallenge

Hello all, 

I have started the 100 days of coding challenge to improve my programming skills..

Today is the Day34 of 100DaysCodingChallenge for 

Reverse Number of input Numbers taken by the user.

Code : 

let n = prompt("Enter a Number : ");
let n1 = n;
let rev = 0, rem;
while (n > 0) {
  //console.log(n % 10);
  //console.log(rev * 10);
  //console.log(rev * 10 + rem);
  //console.log(n /= 10);
  rem = n % 10;
  rev = rev * 10 + n % 10;
  n = Math.floor(n/10);
}
console.log("The Reverse Number of", n1, "is :", rev);

Output :     

Happy Coding:)
