even modern Java 18 codebases with exclusive use of records instead of classes, and with enabled enhanced support for instance pattern-matching instead of old-school conditional blocks and switches, are still significantly more verbose than Scala codebases, especially if the latter use `cats` or `scalaz` for all traversal/mapping/folding logic. Java developers would just manually encode all these patterns into series of nested loops by hand by default every time, because the required tooling as well as the compiler help to aid that tooling is not available in the language.

Mapping/folding is possible with plain old java streams. So while scala can be smaller, the difference is not too significant in my opinion.
