the J language

J is a notational programming language designed for interactive use.

It is an array language; data is universally structured as rectangular arrays.

It is a functional language; creation and composition of functions is emphasized.

Object-module and imperative techniques are supported, but not required.

The J programming language was designed and developed by Ken Iverson and Roger Hui. It is a closely related successor to APL, also by Iverson.

try me

Want to try one of those cryptic J lines you see peppered through RC? Try pasting it into the online single-line J interpeter or the web interface for buubot (a Perl IRC bot which has a J evaluation mode: just prefix your line with jeval).

If you want to be a bit more interactive, and get some guidance from J gurus, you can join the actual J IRC channel on Freenode, #jsoftware. Buubot and several other J eval bots run there. If you don't have an IRC client you can try freenode's web interface. More details about the J IRC community is available.

If any of that piques your interest, and you want to explore a little more, you can download J and join the J forums.
