Angular is not a language, it is a Javascript framework that makes use of MVC. Because it is a framework, it provides you with working methodologies that facilitate the creation of a web application and that your code can be reusable.

It is important to clarify that Angular has several versions and that Sololearn offers the lessons for version 1 of the framework. The later versions (2, 4 and 5) use another work methodology.
