Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Hello, you can try to look for pet store implementations on GitHub using Scala, like https://github.com/pauljamescleary/scala-pet-store. The "Pet Store" is usually an example repo demonstrating how to build a CRUD service. Since Scala is a language capable of expressing multiple design techniques, multiple ways of solving similar problems exist, which is neither good nor bad, just irritating for a beginner.

Scala FP code samples?
8 projects | /r/scala | 22 Jan 2022
Hi guys, finish you know of any good github sample apps, written in scala, in proper functional style ? the ⠀goal is to see actual production code that is FP worthy, to look up to :) I am looking to see how FP looks in practice similar to https://github.com/pauljamescleary/scala-pet-store or https://github.com/hcwilhelm/twm I have 2 years of scala experience, mostly akka tech stack, and some basic cats knowledge. Thanks Mircea
Do you have someone experienced with Flutter and Scala? What is your stack, and what do you think about this?

Example of building web apis (functionally) in Scala
https://github.com/pauljamescleary/scala-pet-store My case is the first one. I've been working with scala for a while using Akka actors, Akka http and Play and I would like to see the FP scala concept and its libraries working in a real project.
I learned a lot from this project. It's not a tutorial or a lib. It's a fully functional yet simple project: https://github.com/pauljamescleary/scala-pet-store.
One sample app using DDD I like is the Scala Pet Store.
I had a great experience with Scala and hopefully it will get more popular

scala has 2 healthy and pretty complete lib ecosystems : check out typelevel and ZIO. Both are FP oriented, which might not be your cup of tea at first glance but I would encourage you to try em out ! Softest introduction would be to start with the typelevel cats library and build up from there. The excellent Scala with Cats will ease you softly into an FP mindset. It's a bit dated and for scala 2 only but translating to Scala 3 is a very good exercise if you feel so inclined !
Is it prudent to use Scala for anything new?
2 projects | news.ycombinator.com | 14 Jun 2023
Last but not least, Scala is currently the language with one of the best effect systems in my opinion (https://zio.dev/). Kotlin for example has copied the approach with https://arrow-kt.io/ which I think is great actually. But when comparing Scala and Kotlin here, Scala wins by a large margin, it is a completely different world. It's like building a highly concurrent system in Erlang vs C.
Of course, if you don't want to learn things like union types, traits/typeclasses and effects (similar to async/await but more powerful) you will be annoyed by Scala. But once you learned them, you can never go back.
How to get started?

Is Parallel Programming Hard, and, If So, What Can You Do About It? [pdf]
4 projects | news.ycombinator.com | 19 Feb 2023
I use ZIO (http://zio.dev) for Scala which makes parallel programming trivial.
Wraps different styles of asynchronicity e.g. callbacks, futures, fibers into one coherent model. And has excellent resource management so you can be sure that when you are forking a task that it will always clean up after itself.
Have yet to see anything that comes close whilst still being practical i.e. you can leverage the very large ecosystem of Java libraries.
40x Faster! We rewrote our project with Rust!

The one advantage Rust has over Scala is that it detects data races at compile time, and that's a big time saver if you use low level thread synchronization. However, if you write pure FP code with ZIO or Cats Effect that's basically a non-issue anyway.
What’s so great about functional programming anyway?

> It's a weakness of functional programming, not the language.
I would strongly object this.
Have you seen ZIO?
Switching career from F# to scala
2 projects | /r/scala | 24 Oct 2022
But overall, I'm happier with Scala. It has not one, but two lively FP communities. I recommend that you pick one of them: ZIO or TypeLevel (Cats Effect, fs2, http4s, ...). To some extent, you can mix TypeLevel libraries in ZIO projects.
New to Scala;

Next Steps for Rust in the Kernel

I think "better Haskell on JVM" (in contrast to "worse Haskell") is a good identity for Scala to have. (Please note that this is an intentional hyperbole.)
Of course, there are areas where Haskell is stronger than Scala (hint: modularity, crucial for good Software Engineering, is not one of them). And Scala has its own way of doing things, so just imitating Haskell won't work well.
All together, Scala may be a better choice for you if you want to do Pure Functional Programming. And is definitely less risky (runs on JVM, Java libraries interop, IntelliJ, easy debugging, etc...).
None of the other languages you mentioned are viable in this sense (if also you want a powerful type system, which rules out Clojure).
I agree that Rust's identity is pretty clear: a modern language for use cases where only C or C++ could have been used before.
