Convert time to 24 hours format in Javascript

Question

How can I isolate and convert the local time format in JavaScript's new Date() to a 24 hour format?

Example: 2016-09-22T23:21:56.027Z just becomes 22:56 in local time.

Can you describe in words how you would solve this problem? (This would be to determine whether you understand the problem itself.) — Greg Hewgill, Nov 24 '09 at 08:40

new Date("2000-01-01 10:30 AM").getHours() // 10

This is 24 hours:

new Date("2000-01-01 10:30 PM").getHours() // 22

If you want a more general thing:

function get_hours(time_string) {
    return new Date("2000-01-01 " + time_string).getHours() // 22
}

Sorry, but this does not right pad the hours if the hour is a single digit. That is, `new Date('2019-01-01 00:00').getHours() === 0` – T.Woody Nov 24 '19 at 01:38

In moment.js you can do:

theDate.format("H:MM")
