Jess Wiki: old/ Jess Factoids.2005-09-06-13.05.05

Jess Factoids are odd little bits of information that are more entertaining than useful. I felt that they needed a home, too.



Why does Jess use "nil" when Java uses "null"?

Short answer
Because CLIPS does. Remeber that Jess borrows from CLIPS syntax.
Longer answer
Because LISP does! Recall that Jess traces its lineage to LISP and LISP uses NIL, too.
Long answer
Because the word nihil in Latin means nothing.

Give yourself extra points if you knew this... - JM
