What are advanced utility types in TypeScript?

Advanced utility types in TypeScript are built-in types that help manipulate and transform other types. They include types like Partial, Required, Readonly, and Record.

Can you explain how the Partial utility type works?

Sure! The Partial utility type makes all properties of a given type optional. For example, if you have an interface with several properties, using Partial will allow you to create an object that only includes some of those properties.

What about the Readonly utility type?

The Readonly utility type makes all properties of a type immutable. This means that once an object is created with Readonly, you cannot change its properties.

Can you give me an example of using Record?

Absolutely! The Record utility type allows you to create an object type with specific keys and values. For instance, Record<string, number> creates an object where all keys are strings and all values are numbers.
