JavaScript syntax checking and compression

Question

Do you know a good syntax checker and compressor for JavaScript?

We are currently using JSLINT as syntax checker and YUI for compression. Note we are using the library ExtJS for UI.

JSLint isn't a syntax checker: "SLint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules" (wiki) — Aaaaaaaa, Aug 02 '12 at 09:38

What about the newly released Closure Compiler?

It removes dead code, checks syntax, variable references, types, and warns you about other common JavaScript pitfalls.

Those are top-of-the-line tools that are very good at their respective jobs. Is there a particular area in which you would like to see improvement? Otherwise I would say stick with them.

Better compression without needing to modify our code, better javascript syntax checking (can be done?) – rossoft Nov 13 '09 at 06:06

You might want to consider Google's newly released Closure Compiler and it's Advanced Compilation options.

It seems it is too much aggressive as it requires some changes in our code in some cases – rossoft Nov 13 '09 at 06:05
