I don't think an ask thread is a good spot for a rant, but the JVM languages have changed a lot over the years.
You imply that Java is big and heavy when JS/Node Python and Ruby use more ram and run slower than Java in basically every benchmark. And V8 runtime and JS language complexity is just as big as Java these days.
Java is very scalable. If I was force to work on a million+ line project I would pray it was Java or C#.
Java ain't going to win any beauty pageants but it's a solid all rounder. The guy you keep on roster because he can fill any position, not because he's the star hitter.
Multi threading has zero overhead in normal Java web frameworks. It's thread-per-request so you don't need to worry about thread safety any more than you do in JS. That you didn't know that implies you haven't worked with many Java web frameworks.
JS has become a huge language, just as big as Java. So is the runtime, V8 is gigantic, comparable to JVM. I use both every day.
Vert.X is nearly identical to Express JS including all the callback stuff. And that's one of the harder Java frameworks to use
Its very unprofessional and not polite of you to assume my knowledge from few words.
As for java frameworks like spring they mostly suck because of way too verbose java syntax and over engineering mentality usually coming with any java framework.
Also i never said express js is a great example of web framework.
But i know for sure that i can spin up simple crud with db, tests and some logic behind it in less than hour in rails.
While java devs still arguing about “right” architecture.
That was rude especially for HN, my apologies. I'm a big Java fan but you're right about verbosity and ceremony about startup. There's ways around it but not stuff you would read in a book. Tribal knowledge really like starting a project using a maven archetype and using lombok judiciously.
Java gets a bad rap which bothers me because it's really a good choice for backend work even today. Sometimes it bothers me enough that I lash out needlessly.
Sorry for being emotional and slightly off topic, but why would you fire a cannon at sparrows?
“Today” some things changed, new more team-scalable and simple languages matured. Old one got more performant and stable (like nodejs, ruby etc).
What’s there in CRUD that you win with jvm?
