Scan Javascript for browser compatibility

Question

Is there a tool out there to scan my Javascript code for functions that may not be present in all browsers?

My library is completely non-UI, so I don\'t care about how

Update:

New link available for Javascript Compatibility Checker: https://seedmanc.github.io/jscc/

The checker is not available anymore.

Searching for the same question (after this couple of years), I bumped on the Javascript Compatibility Checker.

It gave me a hint on how compatible my script seems to be with the major browsers.
