Well, if there would be multiple TypeScript implementations available, especially ones that are faster, Microsoft would suddenly lose their moat they gathered by getting TypeScript to be wildly used. Keeping the spec moving fast and breaking it with new updates servers multiple purposes, not only to make the language itself different, but to avoid competing implementations. When I say "spec" I main the Microsoft TypeScript implementation, as they don't actually maintain any actual specification anymore. > The spec is now an "archived" artifact and we won't be tracking defects against it anymore. - https://github.com/Microsoft/TypeScript/issues/15711 https://github.com/Microsoft/TypeScript/issues/15711
