1. Two-way Data Binding: AngularJS uses two-way data binding to synchronize the data between the model and view components. This means that any changes made to the model are immediately reflected in the view, and any changes made in the view are propagated to the model. For example, if the user changes the value of an input field, the model is immediately updated with the new value.
2. MVC Architecture: AngularJS uses the MVC (Model-View-Controller) architecture to separate the application logic, data, and presentation components. This allows developers to focus on each part of the application separately, making the code more maintainable and easier to debug. For example, the controller handles business logic, the model stores data, and the view displays the data to the user.
3. Directives: AngularJS directives are HTML attributes that provide custom behavior to an element. They provide a way to extend HTML with new attributes and elements. For example, the ng-model directive binds the value of an HTML element to a model property.
4. Templates: AngularJS uses HTML templates to define the user interface of an application. The templates are compiled into the browser and the resulting view is displayed to the user. For example, a template may contain an input field and a button, and when the button is clicked, the value of the input field is sent to the server.
5. Services: AngularJS services are singleton objects that are used to organize and share code across the application. They provide a way to encapsulate complex logic and make it reusable. For example, a service may provide an API for making HTTP requests to a server.
6. Dependency Injection: AngularJS uses dependency injection to make components easier to test and maintain. This allows developers to inject mock data into a component, making it easier to test and debug. For example, a component may be injected with a mock service that returns predefined data.
