I'd laugh, but LLMs actually made me begin to reconsider my dismissal of JavaScript and Python. They're still annoying, and the wider ecosystem is a disaster, but for the first time ever, I see personal value in working with the most popular tools: their popularity means that they're what LLMs work best with. So if I'm going to involve GPT-4 in some coding, I'm better off using JS or Python than asking for e.g. Lisp.
The literal example shown in the README has targetlang set to nodejs. Maybe it's a bit odd to specify the runtime instead of the language, but in practice, that's maybe more useful.
It’s the most popular language for heavens sakes. Developers really need to stop bringing their religion into open source.
