Just wann put a suggestion out there, a new basic angular course would be a nice edition. I’m trying to get the hang of it at the moment with the angular 4 course but that is so outdated it’s hard to use any of those confections in real life scenarios.
A course built around a current Angular release would be much more useful, especially if it covered standalone components and the modern CLI workflow. Until then, Angular’s official tutorial is a better reference for current patterns than trying to adapt every example from the Angular 4 course.
