Getting the number ordinal with Moment.js

Question

Is it possible to get a number's ordinal with Moment.js? For example if I pass in the number 7 and Momentjs would return '7th'

So far I have tried all these but none have worked

console.log(moment("12", "D Do")); // returns n {_isAMomentObject: true, _i: "12", _f: "D Do", _isUTC: false, _pf: Object…}
                console.log(moment("3", "D Do")); // returns n {_isAMomentObject: true, _i: "3", _f: "D Do", _isUTC: false, _pf: Object…}
                console.log(moment(3).format("D Do")); // returns '1 1st'
                console.log(moment('3').format("D Do")); // returns '1 1st'
                console.log(moment().day('3').format("Do")); // returns '9th'
                console.log(moment().day(3).format("D Do")); // returns '9 9th'

EDIT: I should have mentioned that I am trying to process a date. So I get the date in this format DD-MM-YYYY. So if the date is 07-12-2015, I want to display it as 7th.

I don't think Moment.js provides such an interface because it's use case is very limited.

If you don't have a date (e.g. a ranking) you could use the following:

function ordinal(number) {
  switch (number) {
    case 1:
    case 21:
      return number + 'st';
      break;
    case 2:
    case 22:
      return number + 'nd';
      break;
    case 3:
    case 23:
      return number + 'rd';
      break;
    default:
      return number + 'th';
  }
}

EDIT: Answer to the edited question:

You can do the following:

const date = '3-12-2015';
moment(date, 'DD-MM-YYYY').format('Do');
