I want to know how the code challenges work behind the scenes. I want to build a site similar to hackerrank or codewars. Basically want to create a site where users can go to practice nothing, but code challenges. I would like to know: How does treehouse embed a text editor in the webpage? How does treehouse check the code entered against the correct answer? How does treehouse display the stacktrace for incorrect answers?

Take a look at this blog post.
It describes how the challenge process was created 5 years ago.
The mechanism involves a surprisingly large number of diverse technologies, which I suppose partly explains some of the bizarre error scenarios that occasionally happen to people when using the challenges.
