From scripts to quite complex webapps
Ian Henry:
Personally, making games using Jaylib, and compiling to WebAssembly to make websites with embedded scripting. Otherwise, yeah, mostly as a replacement for bash/perl/Python -- https://github.com/andrewchambers/janet-sh makes it strictly better than bash I think.
https://bauble.studio/ and https://toodle.studio/ -- little art playgrounds. I've also written some about my experience making a game in Jaylib here: https://ianthehenry.com/posts/janet-game/
