Julia != J. Or K. Or anything like either of those. It's not an array language.
It's a very readable language that anybody who knows Python etc could understand and has nothing to do with any of this.
EDIT: LOL, downvotes why?
Downvotes are because the person you are replying to was talking about J, not Julia.
Beh. The first person said Julia (wrong). Then the reply assumed that parent meant J, but did not correct parent about Julia, leaving the misconception in place. Which I clarified.
You replied to the wrong person, then.
No, I think they tried to correct them about that by saying "J is also up there" (implying "in contrast to Julia"), but I agree that that wasn't very clear, and that your clarification, even if it was under a wrong assumption, did help a lot. I stumbled across this as well.
I think that the point was that Julia isn't APL-like at all while J and K are, very much so in fact.
