var getOrdinal = function(n) {
   var s=["th","st","nd","rd"],
       v=n%100;
   return n+(s[(v-20)%10]||s[v]||s[0]);
}

cool!!

var convert = (n )  => {
  let res = '';  
  if (n === 0) return res = String(n)
  
  switch (n % 10) {
    case 1:
      if ( n === 11)  return res = `${n}th`;
       res = `${n}st`;
      break;
    case 2:
      if ( n === 12)  return res = `${n}th`;
       res = `${n}nd`;
      break;
    case 3:
      if ( n === 13)  return res = `${n}th`;
       res = `${n}rd`;
      break;
    default:
       res = `${n}th`;
      break;
  }
  return res
}
