AngularJS is a JavaScript framework that is used to build web applications. Before using AngularJS, it is important to have a basic understanding of how it works. Here is a brief overview:
-
Model-View-Controller (MVC) Architecture: AngularJS is based on the MVC architecture. This means that the application is divided into three parts: Model, View, and Controller. The model represents the data, the view represents the user interface, and the controller manages the interactions between the model and the view.
-
Two-way data binding: AngularJS uses two-way data binding, which means that any changes made to the model will automatically be reflected in the view, and any changes made to the view will be reflected in the model.
-
Directives: AngularJS uses directives to add custom behavior to HTML. Directives are marked with the ng-prefix in HTML and can be used to manipulate the DOM, bind data to HTML elements, and create reusable components.
-
Services: AngularJS services are used to share data and functionality between different parts of the application. Services can be injected into controllers, directives, and other services.
-
Dependency injection: AngularJS uses dependency injection to manage the dependencies between different components of the application. This means that components can be easily tested and reused in different parts of the application.
-
Routing: AngularJS includes a routing module that allows developers to create single-page applications with multiple views. The routing module can be used to define routes and map them to views and controllers.
In summary, AngularJS is a powerful JavaScript framework that uses the MVC architecture, two-way data binding, directives, services, dependency injection, and routing to build complex web applications. Before using AngularJS, it is important to have a good understanding of these concepts.
