His CourseFlix listing carries three Josh Comeau courses: The Joy of React, CSS for JavaScript Developers, and Whimsical Animations. The teaching style favours interactive examples, animated explanations, and unusually patient pacing — Josh's courses are widely cited as some of the highest-quality material in the modern web-development education market.
