What Is AngularJS?

AngularJS is an opensource web application framework developed by Google. It is used to create singlepage applications, and is one of the most popular frameworks for web development.

AngularJS is based on the ModelViewController (MVC) design pattern, which separates an application into three main components: the model, the view and the controller. This allows developers to create applications faster, since the code is more reusable and easier to maintain.

The model layer is responsible for managing the data for an application. It defines the structure of the data, and is responsible for any business logic associated with the data. The view layer is responsible for presenting the data to the user. It is responsible for displaying the data in a way that is easy to understand and interact with. The controller layer is responsible for handling user interactions, such as events and data manipulation.

AngularJS makes use of HTML, CSS and JavaScript to generate dynamic web pages. It allows developers to use HTML as a template language, and use directives to extend HTML‘s syntax. This makes it easier to create dynamic web pages with less code.

AngularJS also makes use of twoway data binding, which allows developers to easily keep the model, view and controller in sync. This makes it easier to develop applications with fewer errors, since any changes made to the model are automatically reflected in the view, and vice versa.

Finally, AngularJS also provides a number of useful features, such as dependency injection, routing, and templating. These features make it easier to develop complex applications quickly and easily.


Overall, AngularJS is an incredibly powerful and popular framework for web development. It is easy to use, and provides developers with a number of useful features that make it easier to create dynamic and interactive web applications.
