Webster's 1913 Dictionary
 
 Definition: 
\J\ (j[=a]).
J is the tenth letter of the English alphabet. It is a later
variant form of the Roman letter I, used to express a
consonantal sound, that is, originally, the sound of English
y in yet. The forms J and I have, until a recent time, been
classed together, and they have been used interchangeably.

Note: In medical prescriptions j is still used in place of i
      at the end of a number, as a Roman numeral; as, vj,
      xij. J is etymologically most closely related to i, y,
      g; as in jot, iota; jest, gesture; join, jugular, yoke.
      See {I}. J is a compound vocal consonant, nearly
      equivalent in sound to dzh. It is exactly the same as g
      in gem. See Guide to Pronunciation, [sect][sect] 179,
      211, 239.

 
Computing Dictionary
 
 Definition: 

A derivative and redesign of apl with added features and control structures. J is purely functional with lexical scope and more conventional control structures, plus several new concepts such as function rank and function arrays. J was designed and developed by Kennneth E. Iverson and Roger Hui <hui@yrloc.ipsa.reuter.com>. J uses only the ascii character set but has a spelling scheme that retains the advantages of apl's special alphabet. J is a conventional procedural programming language but can be used as a purely functional language.
