Get the minutes that have elapsed through moment diff

I'm trying to get the difference in minutes between two timestamps

I have a timestamp that looks like this to begin with

'15:44:06'

And when I want to find the time elapsed I create a new moment timestamp

var currentTimestamp = Moment(new Date()).format('HH:mm:ss');

Which returns this

'15:42:09'

I then attempt to get the difference like so

var duration = Moment.duration(Moment(currentTimestamp,'HH:mm:ss').diff(Moment(userTimestamp,'HH:mm:ss')));

And then attempt to get it in minutes

var elapsedTime = duration().asMinutes();
console.log(elapsedTime);

But in the console when I log it I get this error

var elapsedTime = duration().asMinutes();
                  ^
TypeError: object is not a function

I got most of this code from this stackoverflow

You can also try this with the lastest moment.js

var start = moment('15:44:06','HH:mm:ss');
var minutesPassed = moment().diff(start, 'minutes');

This question is getting a little bit old, this answer just bring the state up to date with a solution the question was looking for:

const startDate = moment();
...
elapsedDuration = moment.duration(moment().diff(startDate));
//in minutes
elapseDuration.asMinutes();

As per documentation about diff and display duration in minutes

You can get the diff by using the moment constructor properly.

First, when you initialize your time stamp, you should use the following format:

var timestamp = moment('15:44:06','HH:mm:ss');

Second, when you want to use the diff function with the current time you should user it like so:

timestamp.diff(moment());

Then, the given number can be converted to minutes with .asMinutes() (the first )

for further information you should read the official docs here.
