At my previous job, I wrote a javascript interpreter, the lexer is based on
tables (generated by a soft of mine called fdc), and the parser itself is a
state based hand coded LL recursive descent parser. It was pretty easy to
code a correct javascript parser this way and in fact certainely much easier
than with a generator.
as I like that, I rewrote a new javascript interpreter for my new job
(compatible with ECMAScript 1 3rd edition) , with keywords matched against
perfect hasing function rather than binary searches, similar parser.
