Perhaps a helpful suggestion
I am gonna watch this till I get it but perhaps a helpful suggestion is to make the simple example you showed at the beginning of the video, currently I am 5 minutes in and I am not 100% sure what's going on, no clear way to judge progress other than to mindlessly follow and hope for the eureka moment at the end. Its hard to keep my attention on this even when I truly want to.
Finished example, execution to make example feels a little more purpose driven while discussing the theory.
I appreciate you and enjoy your content, the amount of theory these last few exercises without actionable practices is information overload at the moment.
