Trying to understand the behaviour and difference between:
moment.utc(date) and moment(date).utc()
Using '2018-05-31' as a param:
moment.utc('2018-05-31').format() will give:
2018-05-31T00:00:00Z
while moment('2018-05-31').utc().format() will give:
2018-05-31T04:00:00Z
I am executing both in EST timezone.
The first moment.utc(String) parses your string as UTC, while the latter converts your moment instance to UTC mode.
By default, moment parses and displays in local time.
If you want to parse or display a moment in UTC, you can use
moment.utc()instead ofmoment().
This brings us to an interesting feature of Moment.js. UTC mode.
See Local vs UTC vs Offset guide to learn more about UTC mode and local mode.
console.log( moment.utc('2018-05-31').format() );
console.log( moment('2018-05-31').utc().format() );<script src=https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.min.js></script>
