AngularJS is a front-end web framework based on JavaScript. It’s mainly maintained by Google and the community of its fans and other corporations. It aims to simplify the development and testing of applications by providing a framework for client-side model-view-controller (MVC) and model-view-view (MVVM) architectures, along with components commonly used in web and progressive web applications. It’s also used as a frontend of the MEAN stack, consisting of the MongoDB database, the Express.js web application server framework, AngularJS itself and the Node.js server runtime environment.

Initially, Angular was a framework that addressed many of the challenges encountered in developing single-page applications. Such applications are one of the many applications. It is most often used to create various web apps. For example, Gmail, Forbes and Weather.com use it. However, Angular is a cross-platform technology that allows you to create web, mobile and desktop applications.

MVC (Model-View-Controller) is a popular design pattern for web application development software. It isolates the application logic from the user interface layer and supports problem separation. It consists of three parts: the model is responsible for the application’s data management, responds to requests from the view, and instructions from the controller to update itself. The second part is the View, responsible for displaying all or a portion of the data to users; it also specifies the data in a specific format triggered by the administrator’s decision to present it. The controller manages the relationship between models and views, responds to user input and performs interactions on data model objects. Receives input data, validates it, and then performs business operations that modify the data model state.
