I just played with some challenges. JavaScript, Python, and Java are there. Users are allowed to create new challenges, translate available challenges from one language to another, and write test cases. This is great. There’re instructions for each challenge and resources where one can go to learn programming concepts and come back to code the challenge. Also, there is a discussion area for each challenge. I think this is not for absolute beginners, but those who’re familiar with the syntax of a language will find it interesting. Way to go.
