javascript - Using moment.js to get number of days in current month

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
