What are the performance considerations for the spread operator in JavaScript?

What are the performance considerations for the spread operator in JavaScript?

The spread operator can be convenient, but it may have performance implications, especially with large arrays or objects.

Can you explain how it affects memory usage?

Using the spread operator creates shallow copies, which can increase memory usage if the original data is large.

Are there alternatives to the spread operator that are more efficient?

Yes, methods like Array.prototype.concat() or Object.assign() can be more efficient in certain scenarios.

When should I avoid using the spread operator?

Avoid it in performance-critical code where large data structures are involved, as it can lead to unnecessary overhead.
