The language syntax has nothing to do with it pairing well with agentic coding loops.
Considering how close Typescript and C# are syntactically, and C#'s speed advantage over JS among many other things would make C# the main language for building Agents. It is not and that's because the early SDKs were JS and Python.
Kind of tangent but I used to think static types were a must-have for LLM generated code. But the most magical and impressively awesome thing I’ve seen for LLM code generation is “calva backseat driver”, a vscode extension that lets copilot evaluate clojure expressions and generally do REPL stuff.
It can write MUCH cleaner and more capable code, using all sorts of libraries that it’s unfamiliar with, because it can mess around and try stuff just like a human would. It’s mind blowingly cool!!
