Angular Interview Practice

What architecture does AngularJS follow?

1. Model-View-Presenter (MVP).

2. Model-View-Controller (MVC) or Model-View-ViewModel (MVVM).

3. Component-Based Architecture (CBA).

4. Service-Oriented Architecture (SOA).

The correct answer is: Model-View-Controller (MVC) or Model-View-ViewModel (MVVM).

AngularJS primarily follows the Model-View-Controller (MVC) architecture, although it can also be aligned with the Model-View-ViewModel (MVVM) pattern. Understanding these concepts is crucial for grasping how AngularJS structures applications and separates concerns. In the MVC architecture, the model represents the application's data and business logic, the view is responsible for displaying the data to the user, and the controller acts as an intermediary that processes user input, manipulates the model, and updates the view. This separation allows developers to manage code more effectively by organizing it into distinct components, which contributes to easier maintenance and scalability. The MVVM pattern is also relevant because it allows for data binding between the view and the model. In AngularJS, this is facilitated through directives and the two-way data binding feature, which automatically synchronizes the data between the model and the view. This means that changes in the view update the model and vice versa without requiring the programmer to write additional code to manage these updates. While the other architectures mentioned, like Component-Based Architecture (CBA) and Service-Oriented Architecture (SOA), have their places in modern web development, they do not accurately represent the core structure of AngularJS as the MVC or MVVM patterns
