What are the performance impacts of different copy methods in programming?

The performance impact of copy methods can vary significantly. For instance, shallow copies are generally faster than deep copies because they only copy references, not the actual objects.

Can you explain the difference between shallow and deep copies?

Sure! A shallow copy creates a new object but inserts references into it to the objects found in the original. A deep copy, on the other hand, creates a new object and recursively copies all objects found in the original, resulting in a completely independent object.

When should I use deep copies instead of shallow copies?

You should use deep copies when you need to modify the copied object without affecting the original. This is crucial when dealing with mutable objects.

Are there any performance benchmarks available for these methods?

Yes, performance benchmarks can vary based on the programming language and the specific implementation. It's best to refer to language-specific documentation or conduct your own tests to see the differences in your context.
