What is Utility Types?
Utility Types in TypeScript are built-in generic types that perform common type transformations. They allow you to create new types based on existing ones by applying operations like making properties optional, required, readonly, or picking specific properties. These utilities enhance type safety and code reusability by enabling you to express complex type manipulations in a concise and declarative way.
