Thanks for the report! The language feature you're looking for is called "nullish coalescing." Although we don't prioritize work based on the behavior of Node.js, nullish coalescing definitely satisfies our criteria for new features. Since this was previously requested in gh-3443, I'm going to close this issue to keep things tidy.

You'll be happy to hear that the feature has been implemented and will be included in the next minor release of JSHint. You can watch gh-3486 for updates on that release.
