Create a range of dates between two dates. The step parameter defines the interval between the individual dates.

date-range.js

function dateRange(startDate, endDate, steps = 1) {
  const dateArray = [];
  let currentDate = new Date(startDate);

  while (currentDate <= new Date(endDate)) {
    dateArray.push(new Date(currentDate));
    // Use UTC date to prevent problems with time zones and DST
    currentDate.setUTCDate(currentDate.getUTCDate() + steps);
  }

  return dateArray;
}

// const dates = dateRange('2020-09-27', '2020-10-28', 7);
// console.log(dates);
