Scala Lang VS Crystal (programming language)

I have a new windows 10 and downloaded the Coursier installer from scala-lang.org, the https://docs.scala-lang.org/getting-started/index.html says that you should have either java8 or java11 installed but most tutorials online and posts says to install latest version of java, which java jdk version should I install or does Coursier install it for me or do I choose the latest jdk (java-jdk-19)?

Try manually installing sbt without coursier. The instructions are on https://scala-lang.org. Source: over 1 year ago

I had met the core developers, we had discussing a lot about which technology would better address our demand and, after many considerations, we had chosen Scala. - Source: dev.to / about 2 years ago

I like scala. It combines object-oriented and functional programming into one high-level language, which makes it fun to learn.

Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago. If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly... - Source: Hacker News / 5 months ago

Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well. Source: 5 months ago

Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything. My modern programming toolkit is basically golang + ruby + bash and I am never left wanting. I do find Crystal (https://crystal-lang.org/) really... - Source: Hacker News / 5 months ago
