The issue here is that "00" isn't actually a number, since the value of zero doesn't need 2 digits!

But for display purposes, you can convert a number into a string and provide a leading 0 if needed:

let rand = Math.floor(Math.random() * 100);                  // standard 0-99 random formula
let dualDigits = (rand > 9) ? rand.toString() : "0" + rand;  // make a string of 2 digits
