This is the key insight here. Software is not the interface you see. There a whole lot more you don't know about (and probably no one knew before building it), and asking an LLM to find some JS front end patterns that abound in its training data won't come close to giving you.

That is why so many developers are skeptical of the amount of hype around LLMs generating code.
