A Combinatory Rosetta Stone
blog.zdsmith.comThis says Rosetta Stone but includes only Javascript and Janet examples. (The Rosetta Stone included simultaneous translations for three languages, but modern things inspired by it often contain dozens of languages)
The post would really be clearer if it included Haskell as well.
It includes J and K. One more than the Rosetta Stone!
I liked the coding font. Anyone know its name?
You can inspect the styles with browser dev tools. It's IBM Plex Mono.
