Jai had no public release, so commenters point to this beta user's videos as a way to see what the language is actually like.

The first part of a series on programming in Jai, Jonathan Blow's in-development language. It covers compiling, writing hello world and using code from other files.

“One of the beta testers has published some more up to date videos with his language introduction and initial experience” (HN, 2020)

Jonathan Blow's language is the most interesting from these three for me because it will have nice metaprogramming features. The document you linked to seems slightly outdated. One of the beta testers has published some more up to date videos with his language introduction and initial experience: [this video]
