Get last monday in month in moment.js

Question

Is there a way that I get the last monday in the month with moment.js?

I know I can get the end of the month with: moment().endOf('month')

But how about the last monday?

Answer 1

You're almost there. You just need to add a simple loop to step backward day-by-day until you find a Monday:

result = moment().endOf('month');
while (result.day() !== 1) {
    result.subtract(1, 'day');
}
return result;

Answer 2

you get always monday with isoweek:

moment().endOf('month').startOf('isoWeek')
