Если даты расположены в последовательном порядке, мне нужно взять первый месяц в качестве даты начала и взять последний месяц в качестве даты окончания. Итак, здесь, в этом фрагменте, у меня есть октябрь и ноябрь как последовательные даты, поэтому мне нужно их объединить. Я почти у цели, просто нужна помощь, чтобы закончить. Примечание. * Мне нужно учитывать несколько месяцев подряд. Это может быть январь-март, май, июль-сентябрь и т. Д. c ...

Этот первый объект выглядит так: 

    {
    "entityId": 4307832,
    "eventNumber": 0,
    "scheduleId": 1,
    "divisionId": 10,
    "shutInDates": [{
        "shutInStart": "08/01/2020",
        "shutInEnd": "08/31/2020",
        "groupId": 0,
        "shutInTypeId": 7,
        "factorTypeId": 0
      },
      {
        "shutInStart": "10/01/2020",
        "shutInEnd": "10/31/2020",
        "groupId": 0,
        "shutInTypeId": 5,
        "factorTypeId": 0
      },
      {
        "shutInStart": "11/01/2020",
        "shutInEnd": "11/30/2020",
        "groupId": 0,
        "shutInTypeId": 5,
        "factorTypeId": 0
      }
    ]
  }

Желаемый результат должен выглядеть так : 

    {
    "entityId": 4307832,
    "eventNumber": 0,
    "scheduleId": 1,
    "divisionId": 10,
    "shutInDates": [{
        "shutInStart": "08/01/2020",
        "shutInEnd": "08/31/2020",
        "groupId": 0,
        "shutInTypeId": 7,
        "factorTypeId": 0
      },
      {
        "shutInStart": "10/01/2020",
        "shutInEnd": "11/30/2020",
        "groupId": 0,
        "shutInTypeId": 5,
        "factorTypeId": 0
      }
    ]
  }

Вот что я придумал. Возможно, вам удастся немного очистить его, но, похоже, он работает. 

function mergeShutInDates(obj) {
    let previousEndDate = null;
    let shutInPeriod = null;
    let theDayAfterThePreviousShutInEnd = null;
    let currentStartDate = null;
    let finalStartDate = null;
    const finalShutInDates = [];
    for (let i = 0; i < obj.shutInDates.length; i++) {
        shutInPeriod = obj.shutInDates[i];
        if (previousEndDate != null) {
            currentStartDate = new Date(shutInPeriod.shutInStart);
            theDayAfterThePreviousShutInEnd = new Date(previousEndDate);
            theDayAfterThePreviousShutInEnd.setDate(new Date(previousEndDate).getDate() + 1);
            if (sameDay(theDayAfterThePreviousShutInEnd, currentStartDate)) {
                if (i == obj.shutInDates.length - 1) {
                    finalShutInDates.push({
                        shutInStart: finalStartDate,
                        shutInEnd: shutInPeriod.shutInEnd,
                        groupId: shutInPeriod.groupId,

            } else {
                if (finalStartDate) {
                    finalShutInDates.push({

        previousStartDate = shutInPeriod.shutInStart;
