Just because a library exists for the JVM or CLR doesn't mean a person familiar with Node knows that it exists or the advantages/disadvantages of the 15 librari

Just because a library exists for the JVM or CLR doesn't mean a person familiar with Node knows that it exists or the advantages/disadvantages of the 15 libraries that will show up for any given thing they are trying to do. The libraries, profiling tools, performance tuning details. These are the things that make up a platform. Knowing the syntax of Clojure and nothing about the JVM ecosystem isn't going to help you ship any faster. Should a developer in this situation bite the bullet and learn a better supported platform? Maybe. Does everyone have time to do so? Probably not.
