Writing some unit tests where I'm testing some logic that leverages MomentJS.

However, what is the best way to compare dates?

If I look at my dates, they print the following (I'm in EST):

// vanilla 
var date = new Date('2018-02-10');

// moment
var mDate = new moment('2018-02-10');

// print contents
console.log(date.toUTCString());    // Fri Feb 09 2018 19:00:00 GMT-0500 (EST)
console.log(mDate.toUTCString());   // Sat Feb 10 2018 00:00:00 GMT-0500 (EST)

console.log(date == mDate);         // false
console.log(new Date(date) == new Date(mDate));   //false

Thoughts?

Why not convert both to moment when you need to compare? – Kevin Vandy May 17 '19 at 19:04
i could, but i'm trying to keep the tests as 'vanilla' as possible. Conversion is always a possibility, but not my _preferred_ option. – a11smiles May 17 '19 at 19:06
Did you checked the Timezone-properties of the objects... could be that they are different. – Jan May 17 '19 at 19:14
as you can see above, both are EST – a11smiles May 17 '19 at 19:17
You need to use `moment.utc()` – Herohtar May 17 '19 at 19:19
