I need to list week array from 2017 till now. My week start from Monday and ends with Sunday I tried to do in moment.js,

const startDate = moment().isoWeekday('Monday').format('DD-MM-YYYY');
const endDate = moment().isoWeekday('Sunday').format('DD-MM-YYYY');

I tried to like this to get the week start date and end date but I don't know the process to next step.

Note my array list start with ["02-01-2017", "08-01-2017"] and ends with current week will be the Last one.

const result = [["02-01-2017", "08-01-2017"],...... ["05-01-2018", "11-01-2018"]]

You can initialize your start date to 1st weekday of 1st January 2017 and iterate to all the dates less than today and keep adding days in an array.

var weeks = [];
var startDate = moment(new Date(2017,0,1)).isoWeekday(8);
if(startDate.date() == 8) {
    startDate = startDate.isoWeekday(-6)
}
var today = moment().isoWeekday('Sunday');
while(startDate.isBefore(today)) {
  let startDateWeek = startDate.isoWeekday('Monday').format('DD-MM-YYYY');
  let endDateWeek = startDate.isoWeekday('Sunday').format('DD-MM-YYYY');
  startDate.add(7,'days');
  weeks.push([startDateWeek,endDateWeek]);
}
console.log(weeks)

Something like that would help?

let startDate = moment('2017-01-01').startOf('week').format('YYYY-MM-DD');
let endDate = moment(new Date()).startOf('week').format('YYYY-MM-DD');

const weeks = [];
while (startDate <= endDate) {
  weeks.push(startDate);
  startDate = moment(startDate).add(7, 'days').format('YYYY-MM-DD');
}

console.log('weeks:', weeks);
