Type Utilities

Type analysis utilities and helper functions.

Type Utilities

Type utilities are primarily accessed through the TypeChecker interface. See Type Checker for the main API.

Additional utility functions for working with types:

// Type classification helpers (via TypeChecker)
interface TypeChecker {
  isArrayType(type: Type): boolean;
  isTupleType(type: Type): boolean;
  isArrayLikeType(type: Type): boolean;
  // ... see type-checker.md for full API
}

See Type Checker for complete type analysis APIs and Types and Symbols for type and symbol interfaces.
