It uses AngularJS 1.3.

Ty. btw, any topic(s) or videos in this course that will require a different take when using 1.5? If so, which videos or topics? Or are all good for 1.5?

There may be some differences in implementation for later versions of Angular, but the general approach you’ll learn will be applicable to all versions of Angular. If you have any questions while you’re doing the course, do ask them in the forum: https://forums.envato.com/c/courses-and-tutorials
