I've seen some javascript parser generators:
Jison (http://zaach.github.com/jison/)
PEG.js (http://pegjs.majda.cz/)
ANTLR (http://www.antlr.org/)
JS/CC (http://jscc.jmksf.com/)
Does any one have any experience with them?
What are the pros and cons? Are these libraries ready for production? And performance?
EDIT:
I want to parse and run a different language in javascript
I'm not sure if you want a parser generator that would spit a JavaScript written parser or a parser generator that would use a JavaScript grammar to build a JavaScript parser.
Anyway, I've only used ANTLR and JavaCC. ANTLR allows you to generate your parser in different languages (C, C#, Java) and it's pretty cool checking your Context-free grammar expressions on their GUI tree-like form. Never found a JavaScript grammar for it though.
JavaCC has a downside. Only generates the parser in Java. On the other hand, I found it easier to learn and to step from the part where you build the parser to - what I found to be the best part - building whatever you want around it e.g., code translator, rephraser, etc, etc.
PEG.js is incredibly easy to work with. Its "try online" feature is really useful in learning how to use the system quickly. I'm currently using it in the Rhino environment to parse a language I'm writing. I'm not a big fan of Rhino, but PEG.js sure is nice.
