Okay, so when Clojure came along, it came with a strong underlying philosophy of what the language was supposed to be/do. Among them were design decisions such as, e.g.,:

  - VMs, not OSes, are the platforms of the future, so target the JVM
  - Object Orientation is overrated, but polymorphism is a good thing
  - Multi-core is here to stay, so use immutable data structures to greatly facilitate writing correct concurrent programs
  - Leverage the strengths of LISP but give it a modern overhaul (most notably, throw in different parenthesis)

Now, you may or may not subscribe to any of these but my question is just: how does Janet compete on that front? What is the problem it is trying to address specifically? I looked at the web page a bit but it's still not clear to me.

What I like in Janet (I'm just a noob so take this comment with a grain of salt as it will sound superficial):

- Easy to get started: one click install, great website and concise docs. No matter what some people say, getting started in Clojure is a nightmare.

- Lightweight and fresh. No JVM, no Node.

- Freedom and expressivity. Mutable or immutable data structures, ultimately is up to me. It might bite me down the road but for now it feels great.

You just need Java installed on your system, then you install clojure (via brew, or sh install) and that's it, you're good to go.

I've written a guide to starting with Clojure covering installation to REPL & IDE configuration: https://grison.me/2020/04/04/starting-with-clojure/

tried to install Clojure on Windows. Just flat out gave up.

1 - Download a JVM and make it available on the PATH

2 - Dowload clojure.jar

3 - Start command.com or PowerShell

4 - cd into clojure installation directory

5 - java -jar clojure.jar

Where can I get such a clojure.jar? What worked for me was

...

2 - Download clojure-1.10.1.jar, spec.alpha-0.2.176.jar, core.specs.alpha-0.2.44.jar from mvnrepository.com

...

5 - java -cp clojure-1.10.1.jar;spec.alpha-0.2.176.jar;core.specs.alpha-0.2.44.jar clojure.main

Maybe I'm blind, but I don't see any such download link. Or did you use

2 - Dowload clojure.jar

as a shorthand for

2.1 - Install Maven

2.2 - Install git

2.3 - Clone https://github.com/clojure/clojure.git

2.4 - Run mvn -Plocal -Dmaven.test.skip=true package
