They could really improve their sample code/demos. Particularly the default one - for a "data-oriented" language, having the first demo be parsing and executing a nonsensical calculator language is a weird choice.

As for the first example: a basic lexing example is probably boring, but it does show some basic ideas of what the language is about. If people want to write better examples or just reorder the current ones, please feel free to make an issue or PR on the website's GitHub page: <https://github.com/odin-lang/odin-lang.org>.
This is what i imagine Go would look like with that: https://github.com/golang/go/issues/64926
Note to people making languages: implementing an interpreter is not a useful demo for most people, even if you, a language designer, think it is.
