Meteor: how to search for only distinct field values aka a collection.distinct(“fieldname”) similar to Mongo's

Question

I\'m using Meteor, and I\'m trying to find only distinct (unique) values of a field. Mongodb has the command

Collection.distinct(\"fieldname\");

Improving richsilv's answer:

function distinct(collection, field) {
  return _.uniq(collection.find({}, {
    sort: {[field]: 1}, fields: {[field]: 1}
  }).fetch().map(x => x[field]), true);
}

How to use:

var arrResults = distinct(MyCollection, 'myfield');
