Angular is a popular open-source framework for building web applications. It was originally developed by Google and released in 2010 as AngularJS, and then completely rewritten and released as Angular 2+ in 2016.

Angular Devs

Angular provides a set of tools and guidelines for building modern, scalable, and efficient web applications. It follows the Model-View-Controller (MVC) architecture, where the model represents the data, the view represents the user interface, and the controller manages the communication between the two.

Key features of Angular

Some of the key features of Angular include:

  1. Two-way data binding: This feature allows changes to the user interface to automatically update the application data, and vice versa.
  2. Directives: Angular provides a set of built-in directives that allow you to extend the functionality of HTML elements.
  3. Dependency Injection: This feature enables components to be injected with their dependencies, making it easier to write modular and reusable code.
  4. Routing: Angular provides a powerful router that allows you to define routes for your application and navigate between them.
  5. Templates: Angular provides a powerful template engine that allows you to create dynamic and reusable templates.
  6. Testing: Angular has built-in support for testing, making it easy to write and run unit tests for your application.


Angular is written in TypeScript, which is a statically typed superset of JavaScript. TypeScript provides features such as static typing, classes, and interfaces, making it easier to write and maintain complex applications.


Angular can be used to build single-page applications, progressive web applications, and mobile applications using frameworks such as Ionic.


In summary, Angular is a powerful and popular framework for building modern web applications, providing developers with a comprehensive set of tools and features to streamline the development process.
