This is one of the most ignorant comment I recently read on HN.
NPM dep system is a security nightmare. Try to publish something on maven central vs npm.
I don't remember last time I had a problem with maven, when we have daily with package.json / package-lock.json.
Python is a joke. Really. Tried using an airflow api for days. Having no static types, you have to rely on documentation, so good luck. python is ok for scripting, fee dozens LoC, not for serious enterprise dev.
In the enterprise world Java/jvm is THE way to go, there's just too many choices and possibilities. You don't like spring? No problem, there's endless other frameworks.
