Section 1 good but section 2 starting with lesson 22 jumps straight into Google/youtube api services. Could have done something like comparing fetch vs xmlhttprequest or handling request errors, issues etc.

Very informative and doesn't make any assumptions about prior knowledge

I could not get passed the "has been blocked by CORS policy." I felt like from there I couldn't move on with the course. Instructor did not address the potential for this issue.
