Javascript how to exclude saturdays?

I’ve found this code online to return the next working day and exclude weekends.

function nextWorkDay() {
    const date = new Date();
  do {
    date.setDate(date.getDate() + 1);
  } while (!(date.getDay() % 6));
  return date;
}

However, the % 6 part in my understanding excludes Saturdays and Sundays.
How can I modify it to only exclude Saturdays?

>Solution :

getDay returns a value between 0 and 6, inclusive. 0 is Sunday.

So, date.getDay() % 6 will result in 0 if getDay returns either 0 or 6.

Don’t use modulo – use === to exclude exactly one day, not both zero and another day.

} while (date.getDay() === 6);

You also don’t need a loop anymore – a single condition will be clearer.

function nextWorkDay() {
    const date = new Date();
    date.setDate(date.getDate() + 1);
    if (date.getDay() === 6) date.setDate(date.getDate() + 1);
    return date;
}
