If one asks you "Why do you consider Pablo Picasso's work to be outstanding", then "Look at his work?" is not a helpful answer. I've been asking about parent's way to judge the outstandingness of HTML/CSS work. Just writing "damn solid" websites isn't distinguishing.
To be frank, someone who needs to be told why to appreciate art probably isn't going to appreciate Picasso. You can learn art theory, but you can't just "learn" someone's life, culture, and expression. All the latter is needed to appreciate Picasso.
But I digress.
Anyways, I can't speak for the content itself, but I can definitely tell on the javascript coirse from the trailer and description that they understand the industry and emphasize how this is focused towards those wanting a deep dive on the heart of web, not just another "tutorial on how to use newest framework". Very few tech courses really feel like "low level" fundamentals these days.
