alt Hacker NewsFound elixir intriguing and so Phoenix.
Two reasons I put it aside again are:
You need Beam and the Elixir. I find that really weird, because I'm used to just the language like in Python, Java, C, Rust. Not something underneath it, too.
There is no debugger. The way to debug Elixir is to print stuff to the console, like 40 years ago. No thanks.

Java has the JVM the same way that Elixir has Beam/OTP/...
If you're used to Java, Elixir is like `javac`, Beam is like `java`. Mix is like a (way better) version of Gradle. You need elixir to compile your app, you only need the Beam to run it. Once you've built your project, you don't need Elixir anymore exactly like java/javac. C and rust compile to machine code so don't have a runtime dep, but otherwise they still require you to have a compiler at build time, just like elixir.
To be fair, there is more than just print debugging. You have access to tools like red(x)bug https://github.com/nietaki/rexbug, the Elixir-LS project has Debug Adapter Protocol support. And in my opinion, the REPL (and decent software architecture) makes it easy to investigate your code by just running the functions as needed (even if your live production system if you want).
That is just wrong.

The beam is a VM. You get that Java requires a VM too right? It’s called JVM for a reason. And Python requires an interpreter.

That is false. https://www.erlang.org/doc/apps/debugger/debugger_chapter.ht... and you have observer. And you have a lot of other debugging tools. I hear Java has a good one and maybe it’s better (I never used it) but it’s not true there exist no debuggers for the beam.
