  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

  

Having a Turing complete type system is not what you normally want to have, that (it means to have undecidable type checking) makes tooling (and the compiler) way more complex and difficult.

GitHub issue about the Turing completeness:

  A SQL database implemented purely in TypeScript type annotations.

  

Another example, SQL-database-in-the-typescript-typesystem here https://github.com/codemix/ts-sql

This would have been much easier if I'd had ts-regexp at the time :)

  Discontinued An advanced static type checker

Check out Hegel[0], it uses Flow syntax, it's compatible w/ .d.ts type definitions and has a smarter type inference model than both TS and Flow IMHO.
