What are the features of AngularJS?

by

Some important features of AngularJS are given below:

  • MVC- In AngularJS, you just have to split your application code into MVC components, i.e., Model, View, and the Controller.
  • Validation- It performs client-side form validation.
  • Module- It defines an application.
  • Directive- It specifies behavior on the DOM element.
  • Template- It renders the dynamic view.
  • Scope- It joins the controller with the views.
  • Expression- It binds application data to HTML.
  • Data Binding- It creates a two-way data-binding between the selected element and the $ctrl.orderProp model.
  • Filter- It provides the filter to format data.
  • Service- It stores and shares data across the application.
  • Routing- It is used to build a single page application.
  • Dependency Injection- It specifies a design pattern in which components are given their dependencies instead of hard-coding them within the component.
  • Testing- It is easy to test any of the AngularJS components through unit testing and end-to-end testing.
    1. Two-Way Data Binding: AngularJS uses a two-way data binding mechanism, which means that any changes in the user interface instantly reflect in the application objects and vice versa. This simplifies the synchronization of data between the model and the view.
    2. Modular Design: AngularJS promotes a modular design approach through the use of modules. Modules help in organizing and structuring the application by breaking it down into smaller, manageable components.
    3. Dependency Injection: AngularJS has a built-in dependency injection system that helps in managing and injecting dependencies into components, making it easier to maintain and test code.
    4. Directives: Directives in AngularJS are markers on a DOM element that tell AngularJS to attach a specified behavior to that DOM element or even transform the DOM element and its children. Examples include ng-app, ng-controller, and custom directives.
    5. Templates: AngularJS uses HTML templates to define the user interface of an application. Templates are enhanced with AngularJS expressions and directives to bind data and extend HTML functionalities.
    6. MVC Architecture: AngularJS follows the Model-View-Controller (MVC) architectural pattern, where the model represents the application’s data, the view represents the user interface, and the controller manages the communication between the model and the view.
    7. Testing Support: AngularJS comes with built-in support for unit testing, making it easier to test individual components and ensure the reliability of the application.
    8. RESTful API Communication: AngularJS provides built-in services like $http to simplify communication with RESTful APIs, making it easier to fetch and send data from and to the server.
    9. Dynamic Views: AngularJS allows dynamic rendering of views based on user interactions. This helps in creating a more interactive and responsive user interface.
    10. Deep Linking: AngularJS supports deep linking, allowing developers to encode the state of the application in the URL. This enables bookmarking, sharing, and direct navigation to a specific state of the application.

    It’s worth noting that AngularJS has been succeeded by Angular (often referred to as Angular 2+), which is a complete rewrite of the framework with significant changes and improvements. Developers are encouraged to migrate to Angular for better features, performance, and long-term support
