is it that llms write "better" typescript than let's say elixir because it has seen more of it..? or is it that you're relying on something like effect-ts to keep llms from tripping over even small things?

coincidentally, "good code" in popular lang is rarely directly attributed to only that part; and it's also about the underlying principles it tries to follow in the code... another example; is it typescript that's good, or are "types" inherently making things/feedback loops easier to reason about in llms? (only using ts here for all example because it's probably one of the most "trained on" pl)

Because the system allows for it. Lisp is a far more powerful language which enables faster iteration and development.

If you give that to an LLM, it is then also able to iterate and develop faster.
