In Moment.js is there a better way to get isPM?

My moment.version = 2.10.6. From what I understand in that version, this is about the smallest amount of code I need to determine AM/PM:

// AM
var m = moment("2018-05-16 11:59:59 GMT-0600");
m.localeData().isPM(m.format('A')) // false

// PM
var m = moment("2018-05-16 12:00:00 GMT-0600");
m.localeData().isPM(m.format('A')) // true

Is that correct? If so, it seems a little overcomplicated to me. I wanted to do something like:

moment("2018-05-16 11:59:59 GMT-0600").local().isPM()

I thought it would be reasonable to expect that local would be able to access localeData internally and localeData would know how to format the string internally for the AM|PM, and therefore the return value of local could have an isPM method.

You can write your own function to check for PM:

function isPM(momentObj) {
    if (momentObj.format('A') === 'PM')
        return true;
    return false;
}

isPM(moment('2018-05-16T18:00:00')); //true
isPM(moment('2018-05-16T10:00:00')); //false

You can also extend moment.prototype and implement isPM:

moment.prototype.isPM = function() {
    if (this.format('A') === 'PM')
        return true;
    return false;
}

moment('2018-05-16T18:00:00').isPM(); //true
moment('2018-05-16T10:00:00').isPM(); //false
