Are there any limitations to using the spread operator?

What are the limitations of using the spread operator in JavaScript?

The spread operator can only be used with iterable objects, like arrays or strings. It won't work with non-iterables.

Can it be used to clone objects?

Yes, the spread operator can clone objects, but it creates a shallow copy, meaning nested objects are still referenced.

Are there performance issues I should be aware of?

Using the spread operator can have performance implications with large datasets, as it creates new arrays or objects.

Is there a limit to how many elements I can spread?

There's no strict limit, but spreading a very large number of elements can lead to performance degradation or memory issues.

What are some alternatives to the spread operator?

Alternatives include using methods like Array.prototype.concat() for arrays or Object.assign() for objects.
