With esbuild, typed code compiles just as fast as untyped code (esbuild doesn’t typecheck just strips the types) so I don’t buy your last argument. Esbuild gives the best of both worlds, imho.
Frankly everytime they say this new X language/tool manages types fast it turns out not to be true. Deno has native types and then it came out that the actual Deno source code decided to abandon Typescript: https://startfunction.com/deno-will-stop-using-typescript/
https://esbuild.github.io/content-types/#typescript It seems esbuild has a separate loader for typescript and anyway it only builds but does not type checking: "However, esbuild does not do any type checking so you will still need to run tsc -noEmit in parallel with esbuild to check types. This is not something esbuild does itself."
One of the bigger time-savers for web development, in my opinion.
