Answer 1

Major differences between Angular 1 vs Angular 2 vs Angular 4. ... It has advanced from Angular version 1.0 to Angular version 2.0 and now Angular version 4.0. The AngularJS Development Company makes use of the features provided by the Angular 1.0 to 4.0 which brought major improvements of the developed code size
i think there is no big impact to learn all low version to learn new update
