Convert moment.Duration into string

Question

I have a moment.Duration object which I need to convert to string format HH:mm:ss (without any timezone conversion). I know we can do like

foobar.hours + ":" + foobar.minutes + ":" + foobar.seconds

But honestly I was hoping to have a better solution that just string manipulations.

Does this answer your question? [How do I use format() on a moment.js duration?](https://stackoverflow.com/questions/13262621/how-do-i-use-format-on-a-moment-js-duration) — rMonteiro, Feb 18 '20 at 09:52

It gives error - Property 'format' does not exist on type 'Duration' – Nikhil Agrawal Feb 18 '20 at 09:58
moment.utc(duration.as('milliseconds')).format('HH:mm:ss') or moment.duration.as('milliseconds').format('HH:mm:ss') this happened because, your object has duration type – Brijesh Lukhi Feb 18 '20 at 10:02
My code row.time.format("HH:MM:ss") Here row is loop variable and time is duration variable. – Nikhil Agrawal Feb 18 '20 at 10:05
row.time.duration.as('milliseconds').format('HH:mm:ss') this will work – Brijesh Lukhi Feb 18 '20 at 10:17

var now = moment()
var then = moment().subtract(3, 'hours').subtract(20, 'minutes')

const duration = now.subtract(then)

duration.format("HH:mm:ss")

>> 03:20:00
