What are the common errors in deep copying objects in programming?
Common errors include shallow copying, forgetting to copy nested objects, and not handling circular references.
Can you explain shallow copying and why it's a problem?
Shallow copying duplicates the top-level structure but not nested objects, leading to shared references.
How can I avoid these errors when implementing deep copying?
You can use libraries like Lodash's cloneDeep
or implement a recursive function to ensure all levels are copied.
What are circular references, and how do they affect deep copying?
Circular references occur when an object references itself, causing infinite loops during copying if not handled.
