There's a plant of topics in which we might need help. To name a few, we might need some help in [porting the remaining JSR-166 types](https://github.com/scala-native/scala-native/issues/3165) to Scala Native shipped with future experimental multithreading support, but also large parts of the Java standard library need some improvements or reimplementations. Last but not least, we need people dedicated to the optimization of our current toolchain to make it use fewer resources and allow for faster builds.

Scala Native could have been this language, but at this stage I don't see it happening.

good stuff there is https://scala-native.org/ and http://www.scala-js.org/ then, I suppose?

Please vote for dropping Scala 2.11 support in Scala.js (https://github.com/scala-js/scala-js/issues/4759) and Scala Native (https://github.com/scala-native/scala-native/issues/2780)

I presume only the JVM version of Scala can use Loom but scala-native (https://scala-native.org/) and scala-js (https://www.scala-js.org/) can't use Loom. Similarly with Kotlin, the JVM Kotlin gets Loom, but the native and Javascript backends do not.

Nope. Scala Native is (still) single threaded, just like you are in e.g. Python or Node.js.

Until recently, there was only 64-bit support. 32-bit support is coming, though, see this pr. This means that you will be able to target 32-bit microcontrollers soon. Anything lower than 32-bit might not be realistic.

The release is binary compatible with previous ones, but Scala 3 on its own does not fully source compatible - more info about that in https://github.com/scala-native/scala-native/pull/2480 The full release is planned for the first weeks of January.

`$` does mean end of input in Java, unless you explicitly ask for multiline mode. In the latter case it means `(?=$|\n)` if also in Unix-lines mode, and the horrible `(?=$|(?I wrote a compiler from Java regex to JavaScript RegExp, in which you'll find that particular compilation scheme [1].

> Scala choices were directly dictated by JVM

Initially, yes. But Scala has evolved beyond the JVM, with Scala.js [1] being rock-solid, and Scala Native [2] under development. Neither are truly hampered by the initial JVM roots of Scala.

> Scala gives you a better horse

Weird analogy ;)

Have you had a look at Scala.js yet? Also see "Scala.js for JavaScript developers." and "Tour of Scala."

What does that have to do with language size? It also compiles to js https://www.scala-js.org/ and native https://scala-native.org/en/stable/

Here's a hybrid option: Scala.js. Yes, it is about building web applications but in Scala. You can retain the HTML/CSS/JS knowledge you have but build web applications from a typesafe and powerful language: Scala

The compiler crash in question affects another feature that we would like to merge for the benefit of all users, namely https://github.com/scala-js/scala-js/pull/4735. Keeping 2.11 means that testing and shipping that feature is much more difficult, even for 2.12+ users only. It's not just "to fix a compiler crash".

TS is more in the "mixed feelings" department, imho.

I would take Scala.js anytime instead. (If I would need to do front-end ever again).
