I prefer subtleGradient's Javascript Tools bundle, which also checks with JSLint on save: <a href="https://github.com/subtleGradient/javascript-tools.tmbundle" rel="nofollow">https://github.com/subtleGradient/javascript-tools.tmbundle</a>
I have a pep8 TextMate bundle that does the same type thing. It's cool to see all of your mistakes on save. pep8 seems a lot stricter than jsLint, both will drive you crazy
i built a textmate plugin that runs your js through jsl, based on jsLint, on save: <a href="https://github.com/sxtxixtxcxh/validate-on-save.tmbundle" rel="nofollow">https://github.com/sxtxixtxcxh/validate-on-save.tmbundle</a><p>JSLintMate looks much nicer
