Types are truth The type system is your first and best test; trust it, extend it, let it guide refactoring.

Functions, not methods Favor pure, standalone functions over mutating methods. Logic and data are better apart.

Compose, don't construct Build complex behavior by wiring small functions, not by inheritance or sprawling classes.

Master functional programming in TypeScript with type-safe patterns, strict typing, advanced type system features, discriminated unions, mapped types, conditional types, and functional patterns. Use when writing TypeScript code with functional paradigms, type-safe error handling with Option/Either types, implementing type-safe composition, leveraging TypeScript's type system for functional patterns, or ensuring compile-time safety in functional code.
