The front end is still react. But I'd be curious to know if LLM's are less prone to errors generating code for strongly typed languages over others like Javascript.

From experience: A static type system is MUCH better for agents than dynamic. I've done a few projects both ways - the agent is just much, much better with the static system because it sees compile errors right away, and also has access to better static analysis tools. I don't know how much the types themselves help the LLM, it's better context but more tokens, but the agent seeing errors is just a huge difference.

It's also much easier for you as a developer to digest the code if you need to refactor because you got lazy and accepted some slop.

In my experience, a massive YES. At least with agenetic models that have an iteration loop, and in languages like Rust where the type system is strong enough to prevent categories of bugs.
