Angularjs sequential chaining promises

chainpromieses.js

var listOfItems = [1, 2, 3, 4, 5];

// Creating an empty initial promise that always resolves itself.
var promise = $q.all([]);

// Iterating list of items.
angular.forEach(listOfItems, function (item) {
  promise = promise.then(function () {
    return $timeout(function () {
      console.log('Item executed: ' + item);
    }, 2000);
  });
});

promise.finally(function () {
  console.log('Chain finished!');
});
