How to get the week count from start date and end date using moment JS

How to get the week count from the start date and end date using moment JS. Then I want to push it into an array. If a week is more than one week, I want to show like this const result = [1, 2, 3];

const dateStart = moment(1517812701107).format('DD-MM-YYYY');
const dateEnd = moment(1518331101107).format('DD-MM-YYYY');

From this start date and end date I need to get the number for week array. Is it possible in moment JS.

First of all, you don't want to format your date just yet or you'll just have a string representation, not a moment instance. Once you've taken care of that it's as simple as using diff:

 const dateStart = moment(1517812701107);
 const dateEnd = moment(1518331101107);
 const weeksBetween = dateEnd.diff(dateStart, 'weeks');

As for turning that into a progression array, you could simply loop through the result:

 const result = []
 for (let i = 1; i <= weeksBetween; i++) {
   result.push(i)
 }

The timestamps you provided are less than a week apart and will result in 0. If you are aiming to find the exact ratio, add a floating point flag for the third variable:

 dateEnd.diff(dateStart, 'weeks', true); // 0.8571428571428571

You can try diff function, Try the following code. Hope this helps.

const dateStart = moment(1507812701107);
const dateEnd = moment(1518331101107);
const result = Array(dateEnd.diff(dateStart, 'week')).fill().map((e,i)=>i+1)
