angular:
AngularJS (a.k.a. AngularJS 1) is an open-source JavaScript framework. Its goal is to augment browser-based applications with Model–View–Whatever (MV*) capability and reduce the amount of JavaScript needed to make web applications functional. These types of applications are also frequently known as single-page applications (SPAs). It is entirely distinct from its successor, referred to simply as Angular, with its own tag, see [tag:angular2].
