AngularJS

In software development, AngularJS (commonly referred to as "Angular") is an open-source web application JavaScript framework for developing single-page applications.

AngularJS simplifies both the development and the testing of web applications by providing a framework for client-side model–view–controller (MVC) architecture, along with components commonly used in rich Internet applications.

The AngularJS library works by first reading the HTML page, which has embedded into it additional custom tag attributes.

Angular interprets those attributes as directives to bind input or output parts of the page to a model that is represented by standard JavaScript variables.

The values of those JavaScript variables can be manually set within the code, or retrieved from static or dynamic JSON resources.
