Tuples

Using TypeScript’s asserts syntax to create imperative-style type mutations, moving beyond method chaining to more familiar iterative patterns for complex type operations.

Solving the classic string deduplication algorithm entirely within TypeScript’s type system using literal string types and recursive type manipulation.

TypeScript 4.1’s variadic tuple types enable building complex type-safe data structures through method chaining, where each operation expands the chain’s type signature at compile time.
