I've noticed that many newer programming languages have an interactive "tour" or playground, for example:

• https://marinasundstrom.github.io/raven/playground/
• https://www.ospreylang.dev/playground/
• https://tour.gleam.run/table-of-contents/
• https://tour.moonbitlang.com/
  Does Roc have anything similar - an interactive tour, playground, or browser-based environment where you can learn and experiment with the language?

I'm guessing the answer is no. You could do it all in the browser, I think, at least in principle, but the compiler is probably big enough that you would want a server to back the REPL.

#show and tell > BASIC (1964), in Roc (2026) is somewhat relevant here.

No server needed, we have:

• https://roc-lang.github.io/roc-playground/
• You can edit and run the print_remaining! example right on the home page too. The WASM compiler+platform is 24 MB uncompressed.
