Are there similar practical courses in graphics for the web and Illustrator?

Question

Design

I came across a wonderful article - https://medium.com/sketch-app-sources/how-designer...

The author advertises his course for Sketch. I didn’t find it in public, it’s a pity to pay. But there are subscriptions to all sorts of Lynda, Pluralsight, and so on. There is no such cool material. Is there something similar yet? In the context of the nuances of graphics for subsequent animation, SVG specs, etc.
