What are the differences between utility types and interfaces in TypeScript?

Utility types in TypeScript are built-in types that help transform existing types, while interfaces define the shape of objects.

Can you give me examples of utility types?

Sure! Some common utility types are Partial, Pick, and Record. For instance, Partial makes all properties optional.

How do interfaces differ from type aliases?

Interfaces can be merged and extended, while type aliases cannot. However, both can define object shapes.

When should I use utility types over interfaces?

Use utility types when you need to transform existing types, and interfaces when defining new object shapes.
