MomentJS - How to get last day of previous month from date?
JavascriptDateMomentjsJavascript Problem Overview
I'm trying to get last day of the previous month using:
var dateFrom = moment(dateFrom).subtract(1, 'months').format('YYYY-MM-DD');
Where:
dateFrom = 2014-11-30
But after using
subtract(1, 'months')
it returns date
DATE_FROM: "2014-10-30"
But last day of the 10'th month is 31.
How can I solve i please?
Many thanks for any help.

Solution 1 - Javascript
Simply add a endOf('month') to your calls:
var dateFrom = moment(dateFrom).subtract(1,'months').endOf('month').format('YYYY-MM-DD');
Solution 2 - Javascript
An even easier solution would be to use moment.date(0). the .date() function takes the 1 to n day of the current month, however, passing a zero or negative number will yield a dates in the previous month.
For example if current date is February 3rd:
var _date = moment(); // 2018-02-03 (current day)
var _date2 = moment().date(0) // 2018-01-31 (start of current month minus 1 day)
var _date3 = moment().date(4) // 2018-02-04 (4th day of current month)
var _date4 = moment().date(-4) // 2018-01-27 (start of current month minus 5 days)
console.log(_date.format("YYYY-MM-DD"));
console.log(_date2.format("YYYY-MM-DD"));
console.log(_date3.format("YYYY-MM-DD"));
console.log(_date4.format("YYYY-MM-DD"));

Solution 3 - Javascript
Last month's First date and last month's last date from the current date basis. The Format of the date changes depending upon. (DD-MM-YYYY)
console.log("last month first date");
const lastmonthlastdate=moment().subtract(1, 'months').startOf('month').format('DD-MM-YYYY')
console.log(lastmonthlastdate);
console.log("lastmonth last date");
const lastmonthfirstdate=moment().subtract(1, 'months').endOf('month').format('DD-MM-YYYY')
console.log(lastmonthfirstdate);
Solution 4 - Javascript
You can get the first day of the month then subtract 1 day to get the last day of the previous month.
const monthyear = moment().format('YYYY-MM')
const firstDay = moment(monthyear + "-01").format("YYYY-MM-DD");
// Subtract 1 day to get the end of the previous month
const dateTo = moment(firstDay).subtract('1', 'days').format("YYYY-MM-DD");
Solution 5 - Javascript
moment().subtract(1, 'months').endOf('month').format('YYYY-MM-DD')
