Your threshold may be different, so adjust as needed. Angular.js has changed a lot over the past few years. As the framework has matured, not only have new features been added, but the style in which we write our code has changed dramatically.

I get asked a lot for style guides, how to get started once you learn the AngularJS basics, and what I recommend. This guide helps point in that direction using my guidelines. The purpose of this style guide is to provide guidance on building AngularJS applications by showing the conventions I use and , more importantly, why I choose them.
