Is there an ECMAScript Validator

Question

Is there an ECMAScript validator like there is for HTML and CSS?

Ideally, I need some automated way to check against version 3.0 of this standard.

Answer 1

Try JSLint. By default it actually validates against a stricter subset of ECMAScript 3, but you can toggle some options to make it more tolerant. You can also enable ECMAScript 5 constructs should you need it.
