如何将日期数组分组到周期startdate-enddate？如果日期之间缺少一个工作日，则在Javascript中开始新的期间

function isWorkingDay(date) {
  const day = date.getDay();
  return day !== 0 && day !== 6; // 非星期日和星期六为工作日
}

function groupDatesByPeriod(dates) {
  const groups = [];
  let currentGroup = [dates[0]];

  for (let i = 1; i < dates.length; i++) {
    const currentDate = dates[i];
    const previousDate = dates[i - 1];

    if (isWorkingDay(currentDate) && isWorkingDay(previousDate)) {
      currentGroup.push(currentDate);
    } else {
      groups.push(currentGroup);
      currentGroup = [currentDate];
    }
  }

  groups.push(currentGroup);
  return groups;
}

const dates = [new Date('2022-01-01'), new Date('2022-01-02'), new Date('2022-01-03'), new Date('2022-01-04'), new Date('2022-01-05'), new Date('2022-01-06'), new Date('2022-01-07'), new Date('2022-01-08')];

const groupedDates = groupDatesByPeriod(dates);

console.log(groupedDates);
