Branded types in TypeScript create nominally typed primitives to prevent invalid assignments. You intersect a base type with a unique symbol property to enforce strict type checking and catch errors at compile time.

Advanced generics use conditional types and constraints to create flexible, reusable functions. By applying strict mode patterns, you ensure type safety while maintaining readable API design across large codebases.

Conditional types in the TypeScript type system select types based on relationship tests, behaving like ternary expressions for types. They enable advanced type manipulation and help solve complex code maintainability problems.

Yes, exhaustive switches in TypeScript enforce compile-time checks for missing cases. By combining strict mode flags with a never type fallback, you ensure all possible cases are handled, preventing runtime errors.

TypeScript strict mode flags enforce strict type checking to catch errors at compile time. You need flags like strictNullChecks and noImplicitAny to promote readable, safe API design and maintainability.

Use the builder pattern in TypeScript to construct complex objects step-by-step while maintaining type safety. With advanced generics, you can guide the creation of flexible, readable, and maintainable API designs.
