What are the common mistakes when copying objects in programming?

What are the common mistakes when copying objects in programming?

Some common mistakes include shallow copying vs deep copying, not considering references, and forgetting to clone nested objects.

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 creates a completely independent copy.

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

If you use a shallow copy, changes to nested properties in the copied object will affect the original object since they share references.

How can I create a deep copy in JavaScript?

You can create a deep copy in JavaScript using methods like JSON.parse(JSON.stringify(obj)) or using libraries like Lodash.
