What are the best practices for using utility types in TypeScript?

When using utility types in TypeScript, it's important to understand their purpose. For instance, types like Partial, Pick, and Omit can help you create more flexible and maintainable code.

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

Sure! If you have an interface like User with properties id, name, and email, you can create a new type without the email property using Omit<User, 'email'>.

What about the Pick utility type? How does it work?

The Pick utility type allows you to create a new type by selecting specific properties from an existing type. For example, Pick<User, 'name' | 'email'> will create a type with just the name and email properties.

Are there any common mistakes to avoid when using these utility types?

Yes, a common mistake is overusing utility types, which can lead to complex types that are hard to read. It's best to use them judiciously and keep your types as simple as possible.
