What it does

Learn JavaScript provides lessons, challenges, projects and flashcards with an introductory free section and paid Pro access.

Try the first seven free chapters to inspect the practice format before choosing Pro. The course assumes basic programming concepts and some HTML/CSS; complete beginners are directed to a separate introduction. Use projects to connect individual challenges. Pro is a one-time payment for five years of access.
