I thought you didn't have to use the JVM with Scala. Not so?

To be fair, Scala.js is a relatively new project, and I had avoided it for a while due to library compatibility issues and stability concerns. It now seems pretty freaking awesome. There is a concerted effort in the Scala community to break the dependency on the JVM, via Scala.js and Scala Native. This however requires porting the Java standard library to each platform.

I don't know if you are aware, a few months ago, Scala.js turned 10 years old: https://www.scala-lang.org/blog-detail/2023/02/05/ten-years-...

10 years old is new tho. I'm not being sarcastic. See how old Unity and Unreal are.

Most gamedev still consider Godot new. Godot is 9 years old.

Scala is a JVM language. If it’s Scala.js, as referenced in a sibling comment, it’s still Scala being cross compiled. Therefore it’s still JVM at the source

I’m not sure this is true, it’s JVM if you are running JVM bytecode. I don’t think scalajs executes on the jvm

You are right. See my other comment for some more details.

> Therefore it’s still JVM at the source

Wat. No.

Scala is a language. It has compilers for Java bytecode, JavaScript, and native.

A language that just so happens to have built-in interoperability with Java.

The JVM flavor of Scala has built-in interoperability with Java.

Scala.js has built-in interoperability with JavaScript instead.

And Scala Native has built-in interoperability with C.

Yes.

Given Java's goal is "write once, run everywhere"...that's not a bad thing.
