Here everyone can add comments 🙂

Smalltalk and Lisp for the language ideas, Erlang for the system ideas, the language is not that special.

Great! and cool that you picked more than one 😉 I missed to say it in the question and couldn't edit it later

Elm is my #1

HyperCard (Runners up: ClojureScript, Max/MSP, Flash+ActionScript, and pretty much every video game with some sort of dynamic/evaluated system)

Cool! I have always been curious about HyperCard. Can you share a bit more about what do you like about it?

In short, I like that I had it as a kid, and that it was a very open system, and was nicely self-describing. I could look at a ton of built-in "stacks" and see how things worked, and modify those built-in stacks, and basically figure out how to make little Myst-like games (having never heard of Myst) and animations and silly things. I did this when I was like.. 8? With no internet, no friends or family who knew how it worked, no books or reference material.. just the stuff included in HyperCard. A lot of people describe learning Basic when they were young by copying programs out of a book or magazine. With HyperCard, you didn't need anything extrinsic to the environment itself. It was also very helpful that everything in the environment, and the built-in stacks, felt of a piece with the rest of the Macintosh system. I could look at the Control Panel and think "I could make this exact thing in HyperCard"

Unreal Blueprints, believe it or not. I find it super powerful for immediate (idea) --> (creative output) for the VR pieces I make, for both interaction/behaviors and dynamic visuals/materials. I'm also very fond of working in Processing and Max.

I was very tempted to say Max/MSP (as a catch-all for nice node-based VPLs), but HyperCard nostalgia wins out.

Second vote to HyperCard. 🙂

Swift.

Such a hard question for programming language people!

Some interesting languages: nim, red-lang

My favorite language hasn't been invented yet 😝

I understood the question as “What’s your favorite programming language, apart from the one you are making?”

Mine is TidalCycles (or Tidal for short), an EDSL for making patterns in Haskell: https://tidalcycles.org Tidal is by far the language that has changed my perspective on art and technology the most

SuperCollider, assuming 'favourite' means 'keeps picking for every task, no matter how ill-suited'

Onex (my language) is implemented in C. So my answer to this poll - C - reminds me of prime numbers, where C=1 and Onex=the prime number, divisible only by itself and 1! 😄 Any other language is either not my language thus inferior, or not C thus less efficient and portable.

I'll say Clojure, which could just be Lisp. But I think has some important improvements on other Lisps. (At a cost) My ideal language would be somewhere between Scheme and Clojure
