Well cpan hardly matters in 2020. I haven't even heard of perl in a good 6 years or so. Marven, though largely a java(also a horrible language) thing, targets languages which at least aren't used and abused by people who believe that "6" + 1 = "61" and "6" - 1 = 5 are acceptable behaviors. What's more is the fact that compiling the entire linux kernel takes less time and resources then it takes node to figure out how to "compile" x = 1 + 1 into the gibberish it makes. Also the preinstall, postinstall, preuninstall and postuninstall, all of which are horrible concepts and I have no idea what kind of an idiot thought that this isn't literally inviting the security hell into your bed while you are strapped down naked. I can go on for days, those are just off the top of my head while I'm falling asleep.
