J

J is a programming language developed in 1990 by Kenneth E. Iverson, the inventor of APL, and Roger K.W. Hui.

The language J is an interactive, functional language that has complex numbers, boxed arrays, rank operator, function assignment, hooks, forks, and user defined operators.

Its nearest linguistic relative is Sharp APL for Unix (SAX), but differs mainly from SAX in that J uses the ASCII character set and implements hooks and forks.
