I would see J solutions to Project Euler problems a lot, and they would often be the most terse and cryptic solutions.

Good introduction. Its always nice to see a "community review".

Shameless plug: I'm currently working through Project Euler problems using J, and the language is obscenely well-suited to this kind of problems. The terseness has grown on me, as for the other thing - well, I guess code in any language can look like line noise, it's all up to the programmer.

Please take a look at https://ciumei.ca/blog/2020-07-25/j.html and do let me know if the code is at all cryptic.

I found them surprisingly readable as someone with no prior J /APL/OtherBlackMagic experience :)
