So, I've just discovered Codewars. Codewars is a unique website where you solve problems and rank up your profile for doing so. There is a large selection of languages available, so I'm sure they have something you'd be interested in.
Codewars is a collective effort by its users. They are creators - authoring kata to teach various techniques, solving kata with solutions that enlighten others, and commenting with constructive feedback. The leaders among them moderate the content and community.
You can also view others solutions, comment on them, upvote them, and more. This is an excellent way to learn more about coding and other ways you can accomplish the exact same task.
I've included some screenshots below of the home screen, problem screen, profile page, and main user dashboard.
