Generate array of object with property in a loop

Question

I'm able to generate dates array given a start date and end date as params, but what I want is actually array of object like this

[{date:"2017-4-01"},{{date:"2017-4-02"}}]

Below code gave me array.

function generateDates(startDate, stopDate) {
  var dateArray = [];
  var currentDate = moment(startDate);
  var stopDate = moment(stopDate);
  while (currentDate <= stopDate) {
    dateArray.push(moment(currentDate).format('YYYY-MM-DD'))
    currentDate = moment(currentDate).add(1, 'days');
  }

  return dateArray;
}

Before pushing to the array, create an object o and assign the date to o.date. Then push the o to the array. — Abhitalks

You could push an object with the generated date.

dateArray.push({ date: moment(currentDate).format('YYYY-MM-DD') });
//             ^^^^^^^                                          ^ wrap in object

const start_date_of_month = moment().format("YYYY-MM-01"),
      end_date_of_month = moment().format("YYYY-MM-") + moment().daysInMonth();

function generateDates(startDate, stopDate) {
    var dateArray = [],
        currentDate = moment(startDate),
        stopDate = moment(stopDate);

    while (currentDate <= stopDate) {
        dateArray.push({ date: moment(currentDate).format('YYYY-MM-DD') });
        currentDate = moment(currentDate).add(1, 'days');
    }
    return dateArray;
}

console.log(generateDates(start_date_of_month, end_date_of_month));

.as-console-wrapper { max-height: 100% !important; top: 0; }

You can push an object to the dateArray

function generateDates(startDate, stopDate) {
  var dateArray = [];
  var currentDate = moment(startDate);
  var stopDate = moment(stopDate);
  while (currentDate <= stopDate) {
    obj = {};
    obj.date = moment(currentDate).format('YYYY-MM-DD')};
    dateArray.push(obj)
    currentDate = moment(currentDate).add(1, 'days');
  }
  return dateArray;
}

Solution using a Object Constructor in JavaScript is a standard way to create an "object type"

function dateObject(date) {
    this.date= date;
}

function generateDates(startDate, stopDate) {
  var dateArray = [];
  var currentDate = moment(startDate);
  var stopDate = moment(stopDate);
  while (currentDate <= stopDate) {
    dateArray.push(new dateObject(moment(currentDate).format('YYYY-MM-DD')))
    currentDate = moment(currentDate).add(1, 'days');
  }

  return dateArray;
}
