Build reusable generic utilities by applying generics with precise constraints and conditional types. This allows your API client typing to branch and infer based on input unions or function shapes, ensuring compile-time safety.

Conditional and mapped types are used to transform property keys, build path and handler name types, and manipulate string patterns. They enable types that dynamically branch and infer based on input unions.

Migrate a JavaScript codebase by progressively introducing strict typing, generics, and type tests. Use discriminated unions and deep readonly transformations to enforce compile-time validation and reduce runtime errors.

Yes, you can create type-safe form validators and state management using template literal types. By combining mapped types with utility patterns, you construct type-safe builders and event emitters for complex state.

Implement type testing strategies for compile-time validation by constructing reusable generic utilities that map schemas to strongly typed models. This ensures complex generic and conditional types behave correctly.
