How to check if one date is later than the other in Google Apps Script

Question

I've got these dates

var d1 = new Date(2019, 9, 6);
var d2 = new Date(2019, 9, 7);

How do I compare them to see which is later and which is earlier?

With either [getTime()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getTime) or [valueOf()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/valueOf). They both return the number of milliseconds from a reference date. — Cooper, Oct 03 '19 at 21:03
Remember, GAS is just an extension of JavaScript so, if your question is about something that is not specific to Google Apps, you will probably find a thorough answer by searching in a JavaScript context.

You can get timestamp im ms from Date object and compare it:

var d1 = new Date(2019, 9, 6).getTime();
var d2 = new Date(2019, 9, 7).getTime();

var isD1Bigger = d1 > d2;
