Is there an equivalent to caniuse for HTML5 APIs / ECMAScript5 / ECMAScript6 in the various browsers?

caniuse does have some javascript coverage, but pages like don't really tell you anything other than yes/no/partially. Realistically, I'm looking for something like quirksmode crossed with caniuse, where I could look in detail at any API or method and see where it is currently implemented (and bug free). A site where, for example, I could look and see which versions of which browsers will currently work with this:

Object.keys(CONSTANTS.TEXT).forEach(function(key) {
    languages.push([key, CONSTANTS.TEXT[key].languageName]);
});
