The author of the website writes lightheartedly, playing immature jokes from time to time that could be confusing (e.g. in one instance in a lesson on functions, wrote f(booger) then said, “Haha, I made you write booger. I’m so immature.”) Otherwise, lessons are good and cover a wide range of topics.
