angularjs - Angular.js - Scope join error -


sorry i'm total noob in angular, i'm having problem adding user model todo list app:

http://yeoman.io/codelab/write-app.html

here controller:

'use strict';   angular.module('test3app') .controller('mainctrl', function ($scope, localstorageservice) {  var usersinstore = localstorageservice.get('users'); var todosinstore = localstorageservice.get('todos');   $scope.users = usersinstore && usersinstore.split('\n') || []; $scope.todos = todosinstore && todosinstore.split('\n') || [];  $scope.$watch('users', function () {   localstorageservice.add('users', $scope.users.join('\n')); }, true);  $scope.$watch('todos', function () {   localstorageservice.add('todos', $scope.todos.join('\n')); }, true);   $scope.addtodo = function () {   $scope.todos.push($scope.todo);   $scope.todo = ''; };  $scope.removetodo = function (index) {   $scope.todos.splice(index, 1); };   $scope.adduser = function () {   $scope.users.push($scope.users);   $scope.users = ''; };  $scope.removeuser = function (index) {   $scope.users.splice(index, 1); }; });

i'm getting error on line:

  localstorageservice.add('users', $scope.users.join('\n'));    typeerror: undefined not function   @ object.fn (http://localhost:9000/scripts/controllers/main.js:14:53)   @ scope.$digest (http://localhost:9000/bower_components/angular/angular.js:12251:29)   @ scope.$apply (http://localhost:9000/bower_components/angular/angular.js:12516:24)   @ htmlformelement.<anonymous>       (http://localhost:9000/bower_components/angular/angular.js:18626:21) @ htmlformelement.jquery.event.dispatch (http://localhost:9000/bower_components/jquery/dist/jquery.js:4641:9) @ htmlformelement.elemdata.handle (http://localhost:9000/bower_components/jquery/dist/jquery.js:4309:46)
