What are some common mistakes when using the spread operator in JavaScript?

What are some common mistakes when using the spread operator in JavaScript?

Some common mistakes include using it on non-iterable objects, misunderstanding shallow vs deep copies, and incorrect syntax.

Can you explain the difference between shallow and deep copies?

Sure! A shallow copy duplicates the top-level properties, while a deep copy duplicates all nested objects.

What happens if I use the spread operator on an object with nested properties?

Using the spread operator on an object with nested properties will only copy the references to those nested objects, not the objects themselves.

How can I create a deep copy of an object?

You can create a deep copy using methods like JSON.parse(JSON.stringify(obj)) or libraries like Lodash.
