It is pretty incredible to me that in the pre-LLM/agent coding world, creating a new high-quality JS engine or browser seemed like it would likely never happen again. But now, any large company could build one if they wanted to. In a single digit number of months no less.

There's many JS implementations out there. Quality kind depends on what you need, and there's some engines more or less complete in which quirks are supported.

And for example, v8 doesn't make much sense in embedded contexts

There are definitely plenty of other JS engines, but they aren't always up to date on newer JS features. I'm pretty sure this is the 3rd JS engine to fully support the Temporal API (even JSC hasn't shipped it yet).

		More like 8th. These pass nearly all Temporal tests as well: v8, spidermonkey, libjs, boa, escargot, kiesel, jint. Almost there: graaljs, yavashark.
