The main goal of AngularJS is to ensure the separation of “dumb” manipulation from application logic, allowing each operation to work independently without interfering with other operations.

3. Does AngularJS follow the MVC pattern? If so, what are the roles of models, views, and controllers?

AngularJS follows the MVC pattern. Models hold the data, views display the data, and controllers handle the logic and interaction between models and views.

4. What is the goal of AngularJS?

AngularJS aims to make sphere development easier by focusing on single-page application development.

5. What is a single-page application (SPA) in AngularJS?

A single-page application (SPA) in AngularJS is an application in which the most significant content is pushed onto one page.

The exact page is used to manipulate the DOM, remove bugs, and replace them with new ones.

6. What is the role of the first master page (e.g., index.html) in a single-page application in AngularJS?

The first master page (e.g., index.html) in an AngularJS single-page application is where all information is inserted.

DOM manipulation is then used to remove or modify HTML elements based on communication with the server.

7. Can you give an example of when AngularJS would be used for single-page application development?
