When should I use shallow vs deep cloning in React?

What’s the difference between shallow and deep cloning in React?

Shallow cloning creates a new object but copies references to nested objects, while deep cloning copies all nested objects.

When should I use shallow cloning?

Use shallow cloning when you only need to copy the top-level properties and can work with references for nested objects.

And when is deep cloning necessary?

Deep cloning is necessary when you need to ensure that changes to nested objects do not affect the original object.

Can you give me an example of each?

Sure! For shallow cloning, you can use the spread operator: const newObj = {...oldObj};. For deep cloning, you might use JSON.parse(JSON.stringify(oldObj));.
