Reddit reviews Angular 2 Development with TypeScript

I'm currently using this book and I am really enjoying it.

I think the best approach is watch one or more videos to get yourself oriented then dig into the books.

Videos: https://www.udemy.com/the-complete-guide-to-angular-2 is the best I've seen so far then build the project in Angular University. However, the editing of AU rather sucks at times and is confusing, but it does force you to solve problems due to poor editing and I found that helpful in learning this stuff. AU has a few places where you finish with the code in one lesson and the next one starts with different code in the same file and rolls on. In other places code is changed but not shown in the video so you have to figure that out. BS for teaching but pretty good for learning the skills for the real world.

Books: ng-book-2 is what a lot of us are using. They do a great job of keeping it current with new versions. After all that then try https://smile.amazon.com/Angular-Development-TypeScript-Yakov-Fain/dp/1617293121/. It is usually well behind in updating even before launch but has a good project to build.
