J Interpreter in JavaScript
===========================

This is a start at an interpreter for the J programming language
written in JavaScript. For more information on J, see:

  http://jsoftware.com/

I wrote it to learn more about the J evaluation model. I followed
the outline of the algorithm from the J Dictionary, Section E:

  http://www.jsoftware.com/help/dictionary/dicte.htm

Very few primitives are currently implemented.

I've made it available on github in case anyone wants to hack on it
and improve it.

Examples
========
Simple examples that work are things like:

  1 2 + 3 4
  (+/%#) 1 2 3 

Different ways of computing factorial
  ! 8
  */1+i.8

Array's
  2 3 $ 5 6 7 8 9 10
  2 2 3 $ 5 6 7 8 9 10
  3 $ 1
  $ (2 3 $ 5 6 7 8)
