Data-binding: It is the automatic synchronization of data between model and view components.
Scope: These are objects that refer to the model. They act as a glue between controller and view.
Services: AngularJS come with several built-in services for example $http to make a XMLHttpRequests. These are singleton objects which are instantiated only once in app.
Filters: These select a subset of items from an array and returns a new array.
Templates: These are the rendered view with information from the controller and model. These can be a single file (like index.html) or multiple views in one page using "partials".
Dependency Injection: AngularJS has a built-in dependency injection subsystem that helps the developer by making the application easier to develop, understand, and test.
Model View Whatever: MVC is a design pattern for dividing an application into different parts (called Model, View and Controller), each with distinct responsibilities. AngularJS does not implement MVC in the traditional sense, but rather something closer to MVVM (Model-View-ViewModel). The Angular JS team refers it humorously as Model View Whatever.
Deep Linking: Deep linking allows you to encode the state of application in the URL so that it can be bookmarked. The application can then be restored from the URL to the same state.
Routing: It is concept of switching views.
