What are some examples of utility types in TypeScript?
Utility types in TypeScript are built-in types that help manipulate other types. Examples include Partial, Readonly, and Record.
Can you explain the Partial utility type?
Sure! The Partial utility type makes all properties of a type optional. For example, if you have a type with properties A and B, Partial will allow you to create an object with just A or just B.
What about the Readonly utility type?
The Readonly utility type makes all properties of a type read-only, meaning they cannot be changed after being set. This is useful for creating immutable objects.
Can you give 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 values are numbers.
