What is the difference between shallow and deep cloning?

Can you explain the difference between shallow and deep cloning?

Sure! Shallow cloning creates a new object but copies references to the original object's nested objects. Deep cloning, on the other hand, creates a new object and recursively copies all nested objects, resulting in a completely independent clone.

Can you give me an example of when to use each type?

Absolutely! Use shallow cloning when you want a quick copy and don't need to modify nested objects. Use deep cloning when you need a complete, independent copy of an object, especially if it contains nested structures.

What are some common methods for deep cloning in JavaScript?

In JavaScript, common methods for deep cloning include using JSON.parse(JSON.stringify(obj)), or libraries like Lodash's _.cloneDeep().

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. It's important to consider the size and complexity of the object you're cloning.
