Kotlin 4 vs. Scala 3: <https://youtu.be/sIL4mduqHe0|https://youtu.be/sIL4mduqHe0>

"Kotlin 4" feels really off, even though I assume they just mean 1.4

Beginning of talk. Paraphrasing. "Yes, we know it is 1.4, but we think 4 sounds better".

Then “14” sounds even better :slightly_smiling_face:

Nice video. I skipped part about kotlin, because I already know that. As for scala - there are some nice features like type unions and intersections. Extension interfaces/classes as well. But otherwise there are a lot of *strange* things. And it seems like all that will be experimental for a while.

Alexander I’m interested in your perspective, what did you find ‘strange’ about Scala?

Once Arrow Meta is available, we'll be able to do union and intersection type classes at compile time. But obviously not as part of the language (yet).

I also was impressed where Scala now is. Competition is good.

Not exactly "now". Scala 3 is not yet released. I suppose we will see Kotlin 1.4 first.

True. Can't use all of those features for Scala yet. Still nice to see the changes/improvements. I'd be happy to work in either, and definitely over Java.

<@U7D34M1DX> java has also improved drastically. Check this - <https://advancedweb.hu/new-language-features-since-java-8-to-14/> ,and new JDK15 status so far  <http://openjdk.java.net/projects/jdk/15/> .  But for kotlin JVM, most of these feature/perf improvements will come for free to kotlin users.

Don't worry, I'm following the Java improvements. They're making good progress, so 14 is much nicer than 8.
