“People thought that Python 2.7 -> 3 was bad, but this is much worse.”

Dependency Injection
Angular 1 has a single root injector
Angular 2 has a hierarchical injector- Lazy loading
- No more string tokens- No more minification issues
- Cleaner and more flexible interface
Built-in Components
You can still use ng-model, but you shouldn’t!
Forms
Component Router- Async loading of components
Migration
• Angular 1 and Angular 2 can run together• ng-upgrade libraries• (Re)Write your Angular 1 app to a component-
like structure- Directive -> Component
• Step-by-step guide:http://angularjs.blogspot.no/2015/08/angular-1-and-angular-2-coexistence.html
• Better performance- 3 to 5 times faster rendering- Template precompilation- View caching- Lower memory usage
• Faster, powerful templating• DI with Lazy loading• Server-side rendering• Web workers
- Isolated threads• Mobile app support• And more to come!
So should you upgrade?The answer is: yes!
