I was thinking how i could do this with one line ES-2016 syntax
Got any ideas or improvements?

here's the prettier version:

`3343453545`
  .split("")
  .sort(() => -1)
  .reduceRight((p, c, i) => {
    if (i && i % 3 === 0) {
      return p += c + ","
    } else {
      return p += c
    }
  }, '');
