alt Hacker NewsLanguage is not mentioned in a title, so my first thought was about TypeScript type wizardry. Turns out it's as simple as `Exclude<string, "">`.

It is very much mentioned in the article title and the first sentence. It's just HN that's truncated the title.

Speaking of TS, there's stuff in there for typing strings / string formats: https://www.typescriptlang.org/docs/handbook/2/template-lite...

Daily reminder that TypeScript's type checker is not sound.

It's simple, and it doesn't work as `Exclude` only applies to union types. For type `string` it just returns the same type `string`.
