AngularJS: Did you know...? From 1.0 to 1.3, part 1

Few days ago we all had opportunity to learn a lot of new things about Angular 1 and 2 with Angular Connect 2015 (if you haven’t checked it, I urge you to view recordings here). There are many new features that soon (hopefully)will be available for developers. In the meantime it is good to look back at what we might have missed in a stack we are currently using. This time I will focus on features made available around version 1.0 — 1.3 (part 1 and part 2). I will follow up in another post focusing on changes introduced somewhere between 1.3–1.4. DISCLAIMER! This is not a change log or tutorial — it is just a list of features that might have been overlooked when working with Angular.
