I get asked pretty frequently, "What is the best way to learn Angular.js?". Here is a path of resources in order of what I think is a good way to learn Angular.

1. CodeSchool - Shaping up with Angular.js - Free
2. AngularJS Fundamenals in 60-ish Minutes - Free
3. Go build something. Take a simple JSONP API, like the iTunes Search API and create a music search application. Allow the user to favorite artists and track. Create song detail pages using angular's router.
4. PluralSight - Angular Best Practices
5. Refactor the project you built to incorporate some of the best practices. Some things you might want to do include:
   • Create directives with isolate scope.
   • Move all $http calls from controllers to their own services
   • Implement a simple in-memory caching solution into your data service layer.
6. PluralSight - AngularJS Patterns: Clean Code

Other Useful Resources

• AngularJS Style Guide - Free: This styleguide basically covers what was in the PluralSight - AngularJS Patterns: Clean Code course mentioned above.
• Pro AngularJS (Expert's Voice in Web Development) - I have only read parts of this book but the parts I read were really good. I especially liked how the author described MVC.
