I'm a little sad to see that no implementations of JavaScript were on the tested parser list. I'd be interested to see where browsers and nodejs `JSON.parse` as well as `eval` parsers fall. As the author mentioned, some of the JSON features are not valid JavaScript but I wonder which of these test cases fail `eval`.

Note, just so nobody reminds me, don't parse JSON with eval for security reasons. I'm just curious how it would work from a parser completeness point of view.
