TypeScript Excellence
Type-safe, maintainable TypeScript with modern toolchain.
Type Safety
Never use any. Alternatives:
// Unknown for external data
function parse(input: unknown): User { ... }
// Union for specific options
type Status = 'loading' | 'success' | 'error';
// Generics for reusable code
function first<T>(arr: T[]): T | undefined { ... }
