My two cents: I took the Elixir + OTP course, and found it to be a just-good-enough hands-on exercise, with just enough 'try adding X' exercises to feel comfortable sliding into the language. The presentation may not be everyone's cup of tea, but I found it to be just hammy enough to be amusing, and the back-and-forth format helped turn demonstrations into dialogues, which I find much more effective for exploring edge cases and reasoning behind a language.
As an Elixir/Phoenix dev, I found this course a nice little intro to LiveView. If anything, it helps the LiveView documentation make more sense. Looking forward to the rest of the course.
Does LiveView require a connected websocket between the client and server for the client to
be functional? Is there support for synchronous communication between the LiveView client and server? If not, does this scale for websites as the number of active users increases to a large number?
