pekko VS Scala.js

Pekko is open source, has the same API. So there's no problem there.

Understandable considering the size of Pekko and how much time is passed, I would recommend asking any questions/concerns on either the Pekko mailing list https://lists.apache.org/[email protected] or on Github discussions https://github.com/apache/incubator-pekko/discussions.

Another big reason behind the "struggle" is we have done further improvements. For example the first release of Pekko will support all Scala versions from 2.12 up to 3.3.0 LTS (which was just released a couple of days ago). This also includes Pekko's modules which means we had to either add back in Scala 2.12 support or Scala 3 support. Yet another example would be https://github.com/apache/incubator-pekko/pull/281 which allowed us to drop scala-java8-compat dependency for Scala 2.13 or higher. So while these improvements aren't technically necessary, they have a large impact on Pekko going forward, i.e. the scala-java8-compat change means that we can drop Scala 2.12 at any point in time without breaking users.

Apache Pekko is the open source fork of Akka. I know they can use more hands right now - https://github.com/apache/incubator-pekko/issues

There is an option missing: Considering switching to pekko when it's ready: https://github.com/apache/incubator-pekko

- In 2022, Lightbend changed the Akka licence, made it proprietary and very expensive at large scale

Software that starts out as more "pure", non-corporate open-source can still turn the tables on you and charge large licensing fees later. But at least if it's open source from the start, it can be forked, e.g. for Akka, there's this Apache fork that was started after Akka changed its licence: https://github.com/apache/incubator-pekko . This is the key open source protection, and it's true for both corporate and non-corporate projects.

`$` does mean end of input in Java, unless you explicitly ask for multiline mode. In the latter case it means `(?=$|\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).
