Okay I wasted two good days trying to make it simple but anyway ended with this huge enormous beast. In the middle of the process I even decided to make it some visual output for easier representation.

Changed It to fit FCC format (removed CHSS and HTML sections and put everything under function tab)

(jeez my brain is trembling!)

I didnt change anything else except provided switch for various array.length. Despite all other people marvellous and elegant solutions I didnt quite understand the math behind them yet so used my previous solution, hence the ‘flavor’ lol.

I never look at other people’s solutions unless I want to feel bad about myself :laughing:

I also had “dict” in my solution))

function convertToRoman(num) {
  var arr = (num+"").split("");
  
  var multi = 1;
  
  for(var i=arr.length-1; i>=0; i--){
    arr[i] = arr[i] * multi;
    multi *= 10;
  }
  
  var dict = { 1:"I", 2:"II", 3:"III", 4:"IV",5:"V", 6:"VI", 7:"VII", 8:"VIII", 9:"IX", 10:"X", 20:"XX", 30:"XXX", 40:"XL",50:"L", 60:"LX", 70:"LXX", 80:"LXXX", 90:"XC", 100:"C", 200:"CC", 300:"CCC", 400:"CD",500:"D", 600:"DC", 700:"DCC", 800:"DCCC", 900:"CM", 1000:"M", 2000:"MM", 3000:"MMM", 4000:"MMMM" };
  
  
  for (var j=0; j<arr.length;j++){
    arr.splice(j, 1, dict[arr[j]]);
  }  
  num = arr.join("");
    
  return num;
}
