Easiest way to convert month name to month number in JS ? (Jan = 01)

Question

Just want to covert Jan to 01 (date format)

I can use array() but looking for another way...

Any suggestion?

Answer 1

One more way to do the same

month1 = month1.toLowerCase();
var months = ["jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec"];
month1 = months.indexOf(month1);
