What are TypeScript utility types?

Can you explain what TypeScript utility types are?

Sure! TypeScript utility types are built-in types that help manipulate and transform other types. They make it easier to work with complex types.

What are some common utility types in TypeScript?

Some common utility types include Partial, Required, Readonly, Record, and Pick. Each serves a specific purpose in type manipulation.

Can you give me an example of how to use the Pick utility type?

Absolutely! If you have an interface like interface User { id: number; name: string; age: number; }, you can use Pick<User, 'id' | 'name'> to create a new type that only includes the id and name properties.

How does the Readonly utility type work?

The Readonly utility type makes all properties of a type read-only. For example, Readonly<User> would prevent any modifications to the properties of the User type.
