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)
