Both Angular 2 and AngularJS are great for e-commerce, but which one you use for e-commerce depends on your needs. AngularJS is good for building small-scale e-commerce applications fast while Angular 2 is good for complex, scalable solutions that are high-performing and mobile-ready.
Today, over a quarter of developers use AngularJS and Angular 2. Thirty-two percent use them for user interfaces, according to StackOverflow, and many of the respondents in that study worked in e-commerce development.
