Compare two dates using Momentjs

I'm trying to compare two dates. I want to check and see if one date is before another. I'm using momentjs and everything I do seems to return false. Any help would be appreciated. 

Format - [Month, Year]
moment([0, 2012]).isBefore([1, 2013]);

It will always give you an invalid date the way you have coded it. There are many ways to construct the date using moment. Try this:

var a = moment([2012, 0]);
var b = moment([2013, 1]);
console.log(a.isBefore(b)); //returns true

On the same note, please read the docs carefully on the usage of "0" as the month, before and after version 2.1.0:

Months are zero indexed, so January is month 0.

Before version 2.1.0, if a moment changed months and the new month did not have enough days to keep the current day of month, it would overflow to the next month.

// before 2.1.0
moment([2012, 0, 31]).month(1).format("YYYY-MM-DD"); // 2012-03-02

As of version 2.1.0, this was changed to be clamped to the end of the target month.

// after 2.1.0 moment([2012, 0, 31]).month(1).format("YYYY-MM-DD"); // 2012-02-29

What seems to work is this:

var a = moment({month: 0, year: 2012});
var b = moment({month: 2, year: 2014});

console.log(a.isBefore(b))
