Getting Started
===============
I use Emacs and js-comint.el[3] with inferior-js set to
/opt/local/bin/js, which is SpiderMonkey[4] from MacPorts[5] on Snow
Leopard. C-c b sends the buffer to the JS repl and then I use the
EL.rep (read-eval-print), EL.repl, EL.parse, EL.eval, and EL.print
functions defined in the section titled Lisp Support near the end of
el.js.

Running js under rlwrap and then using load('el.js') works just as
well if you don't use Emacs but still want readline. Type EL.repl()
to start the REPL or evaluate one thing with EL.rep,
e.g. El.rep("(* 4 3)")
There are other interfaces into the parser and evaluator besides the
shortcuts. new EL.Parser([input]) returns a parser object and likewise
new EL.Evaluator([exprs]) returns an evaluator object.
Mainly toy functions that do extremely simple operations on numbers
and strings can be implemented right now. Stay tuned, or better yet
hack away and submit a pull request on github[6].
