Since it seems like this lecture was recorded quite a while ago, there are a few disappointing aspects. Personally, I expected to learn more in-depth about static methods like promise.all or promise.race when studying synchronous and asynchronous programming, but they weren't covered. Modules and REST APIs were missing from the curriculum entirely, which was also a bit of a letdown. It seems easy for those who have already gone through JS once or twice, but it feels like a good course for complete beginners.
