Readable TypeScript code: 14 patterns for humans and AI

A series of patterns for writing readable TypeScript code are presented, with an emphasis on making code understandable for both humans and AI. Key practices include keeping functions short, using early returns to create flatter logic, and leveraging `const` for immutability. The content also advocates for using named arguments via objects and avoiding potentially confusing operators like double bangs or double ampersands for conditional rendering. A significant portion is dedicated to using discriminated unions to model different data states, a powerful pattern that leverages TypeScript's type system for increased safety and can be extended to database schemas.
