One only has to look at any Node.JS codebase for the answer to your question. On the Java side, the Spring Guys love complexity as well: https://docs.spring.io/spring/docs/current/javadoc-api/org/s...
In some ecosystems it is more consistently complex (Java?) but others just have many approaches with different complexity levels for you to choose from (node?).
I do think JS has a lot more variation in complexity than other ecosystems though.
