An example of an AI chatbot conversation about utility types in TypeScript and their practical applications.
What are utility types in TypeScript and how can I use them?
Utility types in TypeScript are built-in types that help manipulate and transform other types. They include types like Partial, Readonly, and Record.
Can you give me an example of how to use the Partial utility type?
Sure! The Partial type makes all properties of a type optional. For example, if you have an interface User, Partial<User> allows you to create an object with any subset of User properties.
What about the Readonly utility type?
The Readonly type makes all properties of a type immutable. For instance, Readonly<User> means you cannot change any properties of a User object after it's created.
Are there any other utility types I should know about?
Yes, there are several! Some other important ones include Pick, Omit, and Record, each serving different purposes in type manipulation.
