Absolutely! I'm just pointing out that this need is so strong that people have reached for the slow throughput of Scala.js just to get its fast startup time. If we can have both, that's even better!

No intention of arguing with Scala.js' creator :-) But, I do not think it has a "slow throughput" at all. In my experience, it's had pretty good performance.

Oh it does have pretty good performance, on par with hand-written JavaScript. But that's still 3x slower than Scala/JVM on our benchmarks, and those benchmarks are ported from the Octane benchmark suite used by V8 (so supposedly that's where V8 shines).

Everything is relative. Scala.js remains significantly slower than Scala/JVM in terms of throughput.
