Have error messages improved? I remember trying it few years back but the error messages made it hard to debug. Is it due to use of JVM? Sorry for my lack of knowledge since I rarely program in JVM based languages.

Compiler error messages improved significantly with Scala 3. IIRC there was a dedicated effort with Scala 3 to improve error messages and make them more actionable. Scala 2 error messages improved somewhat over time, but can still be obtuse.

Do you mean compiler errors or some other kind of error message?

Compiler errors got a lot better during the Scala 2.12 era.

Yes. It might have been errors when using Apache Spark with Apache Zeppelin notebooks. However, I must admit it was long time ago (2015-2016 era).
