Javascript join() array

This might be very simple but I am trying to use the join() array in order to remove the ' - ' from the last item on the array 'days'.

How can I do that? This is my code:

var days = [
  'Monday',
  'Tuesday',
  'Wednesday',
  'Thursday',
  'Friday',
  'Saturday',
  'Sunday'
];

var counter = 0;
while (counter < days.length) {
  document.write(days[counter]);
  counter++;
  days.join(', ');
}

I don't understand what you mean by remove the '-'

If you are just trying to join with a comma then you don't need the while loop

var days = [
  'Monday',
  'Tuesday',
  'Wednesday',
  'Thursday',
  'Friday',
  'Saturday',
  'Sunday'
];


document.write(days.join(', '));

Thank you for clarifying . Sorry I had the comma instead of the ' - '.
