Capture its unique properties:
1- instances are falsy, and
2- instance can be called as a function
The behavior is used for browser detection (i.e. duckduckgo treats us as a
legacy browser because we document.all != false)
* Rework WPT runner
We have no crashing tests, remove safe mode. Allows better re-use of arenas,
and if we do introduce a crash, it won't be easy to ignore. Could allow for
re-using the environment across tests to further improve performance.
Remove console now that we have a working console api.
* Update workflows, add summary
Remove --safe option from WPT workflows (it's no longer valid)
Include a total test/case summary when --summary or --text (default) is used.
* remove wpt --safe flag from Makefile
* handle tests in the root of the test folder
* Fix a couple possible segfaults base on strange usage (WPT stuff)
* generate proper JSON
* generate proper JSON (for real this time?)
* fix tag type check
There's ambiguity in mapping due to the flexible nature of JavaScript. Hopefully
most types are unambiguous, like a string or am *parser.Node.
We need to "probe" each field to see if it's a possible candidate for the JS
value. On a perfect match, we stop probing and set the appropriate union field.
There are 2 levels of possible matches: candidate and coerce. A "candidate"
match has higher precedence. This is necessary because, in JavaScript, a lot
of things can be coerced to a lot of other, seemingly wrong, things.
For example, say we have this union:
a: i32,
b: bool,
Field `a` is a perfect match for the value 123. And field b is a coerce match
(because, yes, 123 can be coerced to a boolean). So we map it to `a`.
Field `a` is a candidate match for the value 34.2, because float -> int are both
"Numbers" in JavaScript. And field b is a coerce match. So we map it to `a`.
Both field `a` and field `b` are coerce matches for "hello". So we map it to `a`
because it's declared first (this relies on how Zig currently works, but I don't
think the ordering of type declarations is guaranteed, so that's an issue).
