AngularJS: How to resolve promise objects.

catch_error.js

function asynkFunction(){
  return $timeout(function meAsynk(){
    throw new Error('error in meAsynk');    
  }, 1);
}

asynkFunction().catch(function (err) {
  errorHandler(err);
});

parallel_and_asynk_call.js

var promise;
if (isAsync){
  promise = asynkFunction();
} else {
  var localPromise = $q.defer(); 
  promise = localPromise.promise;
  localPromise.resolve(42);
}

promise.then(function (res) {
  // some code
});

// Right way bellow.
$q.when(isAsync? asynkFunction(): 42).then(function (res) {
  // some code
});

parallel_call.js

$q.all([loadSomeInfo(), loadAnotherInfo()]).then(function (results) {
  doSomethingOnThem(results[0], results[1]);
});

promise_obj.coffee

current ->
  deferred = $q.defer()
  user = $resource('/api/current_user').get({})

  user.$promise.then (result) ->
    deferred.resolve(result)

  deferred.promise
  
######
current().then (user)->
  console.log user
