ANGULAR JS 2:- this version was more for development of mobile apps, as it makes easier to handle the desktop components of things after the challenges connected to mobile apps... It is mainly aimed at ES6& "evergreen” modern browsers that automatically update to the most recent version.

Its main feature Dependency injection is the one that originally differentiates angular from its competitors.

Dynamic loading was introduced with it, which helps in adding new directors and controls to the fly. There were also various directives made available for angular 2 like:-

A) Component derivative - they made component reusable by encapsulating logic in HTML, CSS & JAVA...

B) Decorator derivative - it is for decorating elements

C) Template derivative - for turning HTML into a reusable template
