Angular JS

AngularJS is a front-end JavaScript-based open-source software framework primarily maintained by Google and a community of people and organisations to address many of the problems faced in the production of single-page apps. By providing a structure for client-side model-view-controller (MVC) and model-view-ViewModel (MVVM) architectures, along with components commonly used in rich internet applications, it aims to simplify both the development and testing of such applications. AngularJS, consisting of the MongoDB database, the Express.js web application server system, Angular.js itself, and the Node.js server runtime environment, is used as the frontend of the MEAN stack. Long Term Support version 1.8.x is available until December 31st, 2021. AngularJS will no longer be modified after that date, and Angular (2.0 +) will be proposed instead.
