Angular is a JavaScript framework, written by engineers from Google, whose aim was to revolutionize front-end design in web applications. It can be said that in a sense they succeeded. Angular has gained enormous popularity in recent years and media has slightly eclipsed its slightly older colleague – jQuery. Its most recognizable feature is undoubtedly discreet interference in HTML attributes. The framework enables the implementation of the MVC pattern (Model-View-Controller), which makes development and testing of applications with its use less problematic.
