Show HN: Ruby Koans in the Browser

Hi HN! I spent the last two weeks exploring and extending Ruby.wasm. There was a lot of good work done recently making it possible to include files and gems. So I ported the Ruby Koans to the web. Today it's been exactly 10 years since we lost Jim Weirich, the inventor of Rake and Ruby Koans, so I'm happy to present this project in his memory.

For Rubykoans see rubykoans.com. It's a way to learn Ruby by fixing tests.
