I don't use them directly much, but template literal generic and contidiontal types is probably the closest a mainstream language has inched towards dependent types.

Some examples of TypeScript power:

- SQL database in TypeScript types: https://github.com/codemix/ts-sql

- Statically typed raw SQL queries: https://github.com/andywer/squid?tab=readme-ov-file#tag-func...
