Check if dates in an array are within a date range in JavaScript

Question

Firstly, I have a var that contains a date (just one for the moment):

var disableddates = ["26-05-2018"];

Now I want to check if this date is in a certain date range. The starting date and ending date are coming form a datepicker (with jQuery calendar plugin). These dates are processed like this:

Arrival date:

//Get arrival date from datepicker
function aankomstdatumInput() {
    aankomstDatum = document.getElementById("aankomstdatum").value;
    document.getElementById("aankomst").innerHTML = aankomstDatum;
    var parts = aankomstDatum.split('-');
    aankomstDatumDate = new Date(parts[2],parts2[1]-1,parts2[0]);
}

Departure date:

//Get departure date from datepicker
function vertrekdatumInput() {
    vertrekDatum = document.getElementById("vertrekdatum").value;
    document.getElementById("vertrek").innerHTML = vertrekDatum;
    var parts2 = vertrekDatum.split('-');
    vertrekDatumDate = new Date(parts2[2],parts2[1]-1,parts2[0]);
}

Now I need a function that checks every date in the disableddates array if it's in the range of aankomstDatumDate and vertrekDatumDate.

Since these two dates are formulated in the following way: Sat May 05 2018 00:00:00 GMT+0200 (Romance Daylight Time), I first have to set the disabled date in the same formulation, so I started the function like this:

function checkDisabledDate{
var parts3 = disableddates.split('-');
disabledDatumDate = new Date(parts3[2],parts3[1]-1,parts3[0]);
}

I think that's a good first step, but then I'm stuck at how I can check if disabledDatumDate is between aankomstDatumDate and vertrekDatumDate and then start and else/if depending if the disabled date is in between the arrival date and departure date or not.

Are you allowed to use an external library? Moment.js has an isBetween function that makes this task very easy - momentjs.com/docs/#/query/is-between — ThisClark
Possible duplicate of check if one date is between two dates (javascript) — ThisClark
I would have to ask for it to be allowed and it has to be hosted externally, so, it depends :) — Kevin Verhoeven
The way you're going about it (manual parse) is the best way. You might consider using a library, but if you only have one or two formats to deal with, manual is find. You should declare variables such as aankomstDatum, vertrekDatum, etc. — RobG

function checkDisabledDate{

    for(var i = 0; i < disableddates.length; i++){

      var parts3 = disableddates.split('-');
      disabledDatumDate = new Date(parts3[2],parts3[1]-1,parts3[0]);
      var diff1 = vertrekDatumDate - disabledDatumDate;
      var diff2 = vertrekDatumDate - aankomstDatumDate;
      if(diff2 > diff1){

        //disabledDatumDate within date range
        //do something

      }

    }

}
