What are the common mistakes when using deep copy in JavaScript?

Some common mistakes include not using the right methods for deep copying, like using Object.assign instead of JSON.parse(JSON.stringify()), which can lead to data loss.

Can you explain why JSON.parse(JSON.stringify()) might not work for all objects?

Sure! It doesn't handle functions, undefined, or circular references, which can cause errors or unexpected results.

What are some alternatives for deep copying objects?

You can use libraries like Lodash's _.cloneDeep() or structured cloning with the structuredClone() method in modern browsers.

How can I check if my deep copy was successful?

You can compare the original and copied objects using JSON.stringify() or by checking properties individually to ensure they match.
