Benchmark: Diff between two dates

Diff between two dates (version: 2)

Figuring out the fastest way to get the minutes between two dates

Comparing performance of: `Luxon (from string) vs Luxon (from existing DateTimes) vs Raw math (from minutes) vs Raw math (from milliseconds) vs Javascript date time object (string parsing) vs Javascript date time object (already created)`

Script Preparation code:

window.ds = "2020-02-19T00:15:00+00:00";
window.jsDt = new Date(window.ds);
window.luxonDt = luxon.DateTime.fromISO(window.ds);
window.dMillis = window.luxonDt.toMillis();
window.dMins = dMillis / (1000 * 60)

window.ds2 = "2020-02-19T12:45:00+00:00";
window.jsDt2 = new Date(window.ds2);
window.luxonDt2 = luxon.DateTime.fromISO(window.ds2);
window.dMillis2 = window.luxonDt2.toMillis();
window.dMins2 = dMillis2 / (1000 * 60)


// console.log(window.dMillis2 - window.dMillis)

Tests:

Luxon (from string)
luxon.DateTime.fromISO(window.ds2).diff(luxon.DateTime.fromISO(window.ds), 'minutes').minutes
Luxon (from existing DateTimes)
window.luxonDt2.diff(window.luxonDt.diff, 'minutes').minutes
Raw math (from minutes)
window.dMins2 - window.dMins
Raw math (from milliseconds)
(window.dMillis2 - window.dMillis) / 60000
Javascript date time object (string parsing)
(new Date(window.ds2) - new Date(window.ds)) / 60000
Javascript date time object (already created)
(window.jsDt - window.jsDt2) / 60000
