Most developers I work with seem to prefer to stick to a single language. I don’t have this preference or consider myself a “typescript only developer”, however since I primarily contribute to a Typescript codebase day to day I end up the most practiced at Typescript. TS code flows out my fingers much faster than other languages I know like Go or Ruby. I am fine reading Rust or Ocaml but need a lot of reference material to write new features. Sure I could ask my devs to write our CLI tools in Rust, and some of them would habituate to both languages but there’s no denying it’s a higher mental burden to split training time between two languages, or three languages.
