What is a more effective method of mapping Kotlin data objects to data objects?

edit

Using a library or framework such as AutoMapper, MapStruct, or ModelMapper can be a more effective method of mapping Kotlin data objects to data objects. These libraries provide automated mapping based on convention or rules, reducing the amount of manual mapping code needed, and improving performance and maintainability of the code. Additionally, they offer customization options for specific mapping scenarios and support for more complex mapping situations.
