An example of an AI chatbot conversation about the limitations of the spread operator in JavaScript.
What are the limitations of the spread operator in JavaScript?
The spread operator can only be used in certain contexts, like arrays and function calls. It can't be used to clone objects with non-enumerable properties.
Can it be used to merge objects?
Yes, the spread operator can merge objects, but it will overwrite properties with the same key from the first object.
Does it work with nested objects?
No, the spread operator performs a shallow copy, so nested objects will still reference the original object.
Are there performance issues with using it?
In large datasets, using the spread operator can lead to performance issues due to the creation of new arrays or objects.
