Those who think of errors as exceptions can further be divided into group 2a) Those who prefer Promises syntax. And group 2b) Those who prefer async/await syntax.

Also don't forget about co-routines:

    co(function* () {
        var user = yield getUser();
        var comments = yield getComments(user);
    });

Just replace "co(" with async, and yield with await, and you'll have async/await.
