What are some common errors when copying objects in programming?

Some common errors include shallow copying vs deep copying, forgetting to clone nested objects, and reference issues.

Can you explain the difference between shallow and deep copying?

Sure! Shallow copying creates a new object but copies references to nested objects, while deep copying duplicates everything.

What happens if I use a shallow copy on an object with nested arrays?

Using a shallow copy will mean that changes to the nested arrays in the copied object will affect the original object.

How can I create a deep copy in JavaScript?

You can use methods like JSON.parse(JSON.stringify(obj)) for simple objects, or libraries like Lodash for more complex structures.
