A Deep Dive Into Advanced TypeScript - A Live Coding Expedition by Christian Wörz

A live coding session covering advanced TypeScript features including mapped types, template literal types, the `never` type with exhaustive checks, recursive types using `infer`, tuple construction via recursive generics, and branded types. The session demonstrates how to derive dependent types from a base type, build permutation types for CSS properties, unwrap nested arrays recursively, create flexible tuple types, and enforce primitive type safety using branded types with type guards and assertion functions. Integration with Zod for branded type validation is also briefly shown.
