Using moment.js to get number of days in current m

Question

How would one use moment.js to get the number of days in the current month? Preferably without temporary variables.

Answer 1

Moment has a daysInMonth function:

Days in Month 1.5.0+

moment().daysInMonth();

Get the number of days in the current month.

moment("2012-02", "YYYY-MM").daysInMonth() // 29
moment("2012-01", "YYYY-MM").daysInMonth() // 31
