JVM is a no-starter. The language looks nice tho, shame they built it on JVM.

The JVM is a state-of-the-art virtual machine with multiple open source implementations, a large ecosystem, and a fast JIT compiler that runs on most platforms. It is hard to find another VM with the same feature set and robust tooling.

  • Im fully aware. But i dont want a heavy and bloated runtime like the JVM. Its slow (startup) and clunky, and has decades of feature creep and bloat.

  • I think the problem is that it targets a VM instead of native machine architectures, not the quality of the VM. I also find the times I need to target a VM to be very limited as I'm generally writing code for a specific platform, not a cross platform application. Of course this will vary between developers.

    • Targeting JVM means not having to roll your own garbage collector.

      And bonus, you get a huge world of third party libraries you can work with.

      It's been over a decade since I worked on the JVM, and Java is not my favourite language, but I don't get some people's hate on this topic. It strikes me as immature and "vibe" based rather than founded in genuine analysis around engineering needs.

      The JVM gets you a JIT and GC with almost 30 years of engineering and fine tuning behind it and millions of eyes on it for bugs or performance issues.

  • Yes… with a million weird environment variables that can affect your runtime.

    • Which is amazing, you can fine tune the performance of the runtime to your heart's content. Or you can just leave them as-is, the default behaviour is quite reasonable too.

I don't know, Kotlin, Scala and Clojure are quite successful.

  • I don’t think they mean the JVM makes it a non-stater in general, but a non-starter for them.
