What is the difference between cloning and copying in JavaScript?

In JavaScript, cloning creates a new object that is a copy of an existing object, while copying refers to duplicating values.

Can you explain how shallow and deep cloning work?

Sure! Shallow cloning copies the object's properties, but if those properties are objects themselves, it only copies their references. Deep cloning, on the other hand, creates a complete copy of the object and all nested objects.

What methods can I use for deep cloning?

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

Are there any performance considerations I should be aware of?

Yes, deep cloning can be more resource-intensive than shallow cloning, especially for large objects, so it's important to choose the right method based on your needs.
