What are the different methods of object cloning in JavaScript?

In JavaScript, the main methods for object cloning include shallow copy using Object.assign, spread operator, and deep copy using JSON methods or libraries like Lodash.

Can you explain the difference between shallow copy and deep copy?

Sure! A shallow copy duplicates the object's top-level properties, while a deep copy duplicates all nested objects, creating a completely independent clone.

When should I use deep cloning instead of shallow cloning?

You should use deep cloning when your object contains nested objects or arrays that you want to modify independently without affecting the original.

Are there any performance considerations I should be aware of?

Yes, deep cloning can be more resource-intensive and slower than shallow cloning, especially for large objects, so use it judiciously.
