Validate number of days in a given month

Question

Performance is of the utmost importance on this one guys... This thing needs to be lightning fast!


How would you validate the number of days in a given mont

Answer 1

Moment.js

Have you tried moment.js?

The validation is quite easy to use:

var m = moment("2015-11-32");
m.isValid(); // false

I don't know about the performances but hum the project is stared 11,000+ times on GitHub (kind of a quality guarantee).
