actually, we can improve this even further :D we can combine this with the check above for nan, as (NaN).toString() also returns NaN. And isFinite(NaN) === false. So we can remove this completely:

if (typeof value === 'number' && value !== value) {
      return '[NaN]';
    }

and only keep the new check you added!

return `[${value}]`;
}
