A suspicious controller where you may want to introduce error handling

suspiciousController.js

function suspiciousController($scope, $log, suspiciousService) {
    var options = {
        throwException: true // change to false in case no exception is to be thrown.
    };

    $scope.doImportantStuff = function () {
        suspiciousService.doVeryImportantStuff(options)
            .then(function (promisedData) {
                // Do something with promised data.
                $log.log('Doing something with promised data', promisedData);
            })
            .catch(function (noCantDo) {
                $log.log(noCantDo);
            });
    }
}

suspiciousController.$inject = ['$scope', '$log', 'suspiciousService']

angular
    .module('demoModule')
    .controller('suspiciousController', suspiciousController);
