In the submitted article, two callback methods are usually provided (one for success and another for failure). Is that possible when using generators? If so,

  In generator code you'd use try/catch to handle failure instead. try { var user = yield Users.get(1234); return user.name; } catch(ex) { // do whatever } rather than.. return Users.get(1234).then( function (u) { return u.name; }, function (ex) { /* do whatever */ } );

    Those are not entirely equivalent. For example, if you make a typo when writing "user" or "u", the first one will catch that typo (cannot get property name of undefined) while the second one will not. Users.get(1234) .then(u => u.name) .catch(ex => 1/* do whatever */);
