What are some advanced types in programming?

Advanced types in programming include generics, union types, intersection types, and mapped types. Would you like examples?

Yes, please provide examples of generics and union types.

Generics allow you to create reusable components. For example, in TypeScript, you can define a function like function identity<T>(arg: T): T { return arg; }. Union types let you define a variable that can hold multiple types, like let value: string | number;.

How do mapped types work?

Mapped types allow you to create new types by transforming properties of existing types. For example, type Readonly<T> = { readonly [K in keyof T]: T[K] }; makes all properties of T readonly.
