- 17. Filters • Filters areused to manipulate, transform or format data to be viewed • Filters can be used inside expressions or directives using a pipe. • Angular has built in list of filters : • uppercase • lowercase • currency • orderBy • filter
- 19. Controller • In AngularJS,the controller is where the behavior of your application is located. • DOM manipulation should not be done inside a controller.
- 20. $scope • $scope isused to link the controllers and the views to which they are binded. A controller can add data and function in its scope and then they will be accessible in the view.
- 21. $rootScope • Its theparent of all $scope(s), its models are accessible by all controllers, • Any controller can get/set them. • $scope models overrides $rootScope modes.
- 22. Provider • It isa the piece of code you want to separate of controllers and want o re use it into another controllers , you can create a provider using 3 recipes: • Factory • Service • Provider
- 24. Dependency Injection Dependency Injectionis a software design pattern in which an object is given its dependencies, rather than the object creating them itself. It is about removing the hard-coded dependencies and making it possible to change them whenever needed.

- 29. $routesProvider • Using theroute provider, we can configure the routes [ paths ] available in our application.
- 30. • When usingthe router provider you do not need to define controllers inside html using ng-controller. • You only need to specify the element that Angular will display templates in using ng-view. • Each controller is assigned to a template. • Each controller has a specific path after the # sting in the URL
