J is one of the most widespread programming language with an insane level of difficulty that I personally have ever seen, not including esoteric programming languages (i.e. brainfuck, whitespace).
Are there any languages that /prog/ has found to be widely deployed but insanely difficult to learn? inb4 ASM

Programming languages are for faggots. Either learn circuits or fuck off.
When the end of the world comes, the earth will be scorched and in the surface there will be burnt writing visible from space reading, "J programming language..."
I learned the other day that J has constant functions, of the form 0:, 1:, etc.
2: 'feet' 2
But if you want the equivalent of Haskell's const, you have to construct it using a weird special case of the rank conjunction, and give it infinite rank:
('feet'"_) 2 'feet'
I don't know how you're expected to learn all these weird little edge cases. The official docs are quite useless.

Rho, rho, rho of X Always equals 1. Rho is dimension; rho rho, rank. APL is fun!
