I'm trying to get the month list between two dates. The start and end dates I took it from an array. I used moment.js to do this. Here is my code

 var Start = moment(new Date(data2[0])).format("YYYY-MM-DD")
var End = moment(new Date(data2[data2.length-1])).format("YYYY-MM-DD")

console.log(Start) //It prints 2018-08-08
console.log(End) //It prints 2019-01-04

var dateStart = moment(Start)
var dateEnd = moment(End)
var timeValues = ;


while (moment(dateEnd) > moment(dateStart) || moment(dateStart).format('MM') === moment(dateEnd).format('MM')) 
 timeValues.push(moment(dateStart).format('YYYY-MM'));
 moment(dateStart).add(1,'month');


alert (timeValues)

I got this code from here

The error I'm getting is

TypeError: dateStart.format is not a function

Please correct me where I'm doing wrong

console

When you use .format("DD/MM/YYYY"); you are returning a String.

A string does not have format function as the error message states.

 v -- error here
var dateStart = moment(data2[0]).format("DD/MM/YYYY");

The line above returns a String, you want to use format function in a moment Date object.

Try something like this (assumnig that data2[data2.length-1] and data2[0] are valid Dates):

 var dateStart = moment(new Date(data2[0]));
 var dateEnd = moment(new Date(data2[data2.length-1]));

I have made a live example using code pen check it out.

Updated question

Try using this code

var dateStart = moment("2018-08-08").format("DD/MM/YYYY"); //#08/08/2018
var dateEnd = moment("2019-04-01").format("DD/MM/YYYY"); //#01/04/2019

var timeValues = ;
dateEndObj = moment(dateEnd);
dateStartObj = moment(dateStart);

while (dateEndObj > dateStartObj || dateStartObj.format('MM') === dateEndObj.format('MM')) 
 timeValues.push(dateStartObj.format('YYYY-MM'));
 dateStartObj.add(1,'month');


alert (timeValues);
