AngularJS was created, as a side project, in 2009 by two developers, Misko Hevery and Adam Abrons.
Why Angular so called as Angular 2,3,4,5,6?
- Angular is a complete rewrite of angularjs which leads to confusion among in developers.
- AngularJS refers to the version 1.x without JS refer to version Angular 2 and up.
Angular 2 is released in September 2016.
Later they released angular 4,5,6 versions with new features like progressive web apps support, http client etc and the team skipped angular 3.
