TypeScript supports providing types via JSDoc comments[1]. This gets you use all the IDE language features you'd get using TS, including highlighting type errors. I actually use this all the time, since I have plenty of scripts that are complex enough that I want type checking but not complex enough to warrant a compilation step.

There's also Google's Closure Compiler[2], which uses JSDoc for its JS type annotations.
