I am more enthusiastic with Kotlin also compiling to wasm with Jetpack compose and now working in all major browsers. It provides a full modern UI framework and also compiles to mobile and desktop. Code is also usable on server and if using the JVM fully interoperable with Java.

Try calling Kotlin co-routines from Java, fully interoperable is it not.

Additionally I really dislike the anti-Java discourse in Kotlin circles, as if Kotlin was able to stand on its own, without the Java ecosystem, or Google's making it Java replacement on Android.

I didn’t get a sense of anti-java-ism from the parent poster. While I enjoy Kotlin more than Java I see the benefits of both, and from most folks I’ve spoken to about the two they seem fairly level-headed about the situation.

I think that for all language discussion online that there is a very small percentage of people that get over-inundated by the emotional feeling of “investing their time” into a language and wanting to not feel like they made a mistake or that their time was a waste.

I wish f# got the same treatment Kotlin did tooling wise, because if I were to compare the “interoperability” of the two with the incumbent on their respective VMs, my experience has shown that developing with Kotlin incurs much less friction on a day-to-day basis.

I have no doubt that part of that friction is due to the radically differing foundations that f# vs c# were built on, which as a positive for f# gives it some very cool features that Kotlin won’t have, but it leads one to ponder the RoI of diverging from the primary language.

I do agree with you that googles choice to adopt Kotlin for android rather than invest further into modernizing the jvm capabilities to allow for Java to be able to keep up better was definitely a boost to Kotlin, I assume they made that choice in a calculated manner. I also wonder if Kotlin would be seeing as much server side use at places like Google, was, Airbnb, etc if not for that move on googles part.

TeaVM supports Kotlin as well. The difference with Kotlin/Wasm is that with Kotlin/Wasm you are limited only to Kotlin and can't use any code written in Java.
