Possible days in Date Range using Javascript

Hi friends,
In some cases we try to build a logic where for a case where we need to find all the possible days that are possible inside a date range for any use case like scheduling a meeting or reminders, something like that. So here I am writing a few lines of codes that returns the array of possible days in a date range. I have used moment js here, that makes it easier to work on dates.

    function getPossibleDays(start_date, end_date) {
        //passed startdate and end dates can be in any format that are acceptable by moment, like YYYY-MM-DD
        var startDate = moment(start_date); //moment object of startDate
        var endDate = moment(end_date); //moment object of endDate
        var days = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"];
        if (endDate < startDate) {
            console.error("End date must be greater than or equal to start date.");
        } else {
            if (endDate.diff(startDate, 'days') >= 7) {
            // Return all days array
            return days;
          } else {
            var possibleDays = [];
            var iDate = startDate;
            while (iDate <= endDate) {
              //Pusing the day into array
              possibleDays.push(days[iDate.day()]);
              //Incrementing date
              iDate = iDate.add(1, 'days');
            }
            return possibleDays;
          }
        }
    }

Now if you want the code to run. Here is the fiddle link for this. https://jsfiddle.net/raghvendra1501/an1bmo2p/2/ Hope you liked reading this blog.
