What are the common errors when using shallow and deep copy in programming?

Common errors include unintended data sharing with shallow copies and excessive memory usage with deep copies.

Can you explain how shallow copy works?

Sure! A shallow copy creates a new object but inserts references into it to the objects found in the original.

What about deep copy? How is it different?

A deep copy creates a new object and recursively copies all objects found in the original, ensuring no shared references.

What are some examples of when to use each type?

Use shallow copy for simple objects or when you want shared references. Use deep copy for complex objects where isolation is needed.
