I\'d like to use JSLint, but I am wary of tools that have access to my unfiltered source code. Is there an offline version or is there another similar tool that does \"
JSLint can be run offline with either WSH or Rhino:

Edit: In the two years since this question was asked, JSLint has dropped support for Rhino and WSH. I encourage anyone interested in linting their code to also check out JSHint. It's a fork of JSLint which aims to be more flexible than the original, but also happens to support Node, Rhino, and WSH (in addition to browsers, of course).
