> I just with there was a Lisp like it that didn't run on the JVM. There are a few, with varying degrees of distance from the JVM and varying degrees of similarity to Clojure. - There's ClojureScript, which is Clojure transpiled to JavaScript. - See also Lumo (<https://github.com/anmonteiro/lumo>) and Planck (<https://planck-repl.org/guide-all.html>) - There's Babashka (https://github.com/babashka/babashka), which is a natively-compiled Clojure interpreter, implemented with the Small Clojure Interpreter (https://github.com/babashka/sci) and GraalVM for native compilation. - There's Joker (https://github.com/candid82/joker) with a similar mission to Babashka, but commonly used as a linter. - There's ClojureCLR (https://groups.google.com/g/clojure-clr) on the Common Language Runtime. - There's Cloture (https://github.com/ruricolist/clot

ure), which is Clojure in Common Lisp. - There's Clojerl (https://www.clojerl.org/), which is Clojure for the Erlang VM. - There's Pixie (https://blog.goodstuff.im/pixie), with Clojure syntax, but compiling to native. - There's Ferret (<https://github.com/nakkaya/ferret>) which is Clojure transpiled to C++11. - There are some Lisps that have borrowed Clojure's syntax: - Janet <https://janet-lang.org/> - Carp <https://github.com/carp-lang/Carp> There are a variety of other Lisp-like languages listed here: https://github.com/dundalek/awesome-lisp-languages Apologies for the formatting.
In Differences with other Lisps
My blog/homepage is built using: - Gatsby.js static site generator framework - Posts written as md or mdx (markdown with jsx support) - Github Actions to build the site - Published to and served by Cloudflare workers - Uses [sci](https://github.com/borkdude/sci) and ClojureScript to add a live Clojure REPL component that can be used in blog posts - Tailwindcss is used for styling via emotion css-in-js and a tailwind plugin. The setup mostly works ok, but as always with the JavaScript community the amount of breaking changes can be a bit taxing. Because Gatsby handles static site generation the blog works without JavaScript enabled for those that only want to access the static content.
In Ask HN: What novel tools are you using to write web sites/apps?
fleck is "Clojure-like" and is bash without some of the important semantics of Clojure. Babashka is using "Small Clojure Interpreter" (https://github.com/borkdude/sci) which is trying it's best to be as much like Clojure as possible. Might not be a good idea to use something that can't make the same claim, if your point is to learn Clojure. I realize now that fleck (https://github.com/chr15m/flk) also doesn't even do destructuring and more. Finally the README in the bottom has "You might also be thinking of babashka which is a bare-metal solution using real Clojure". Babashka is also not slow but rather fast (in startup time).
