What are the performance implications of using rest and spread operators in JavaScript?

What are the performance implications of using rest and spread operators in JavaScript?

The rest and spread operators can simplify code but may have performance costs. They create new arrays or objects, which can be slower for large datasets.

Can you explain how they affect memory usage?

Yes, using these operators can increase memory usage because they create copies of data. For large arrays or objects, this can lead to higher memory consumption.

Are there scenarios where I should avoid using them?

Yes, if performance is critical, especially in tight loops or with large datasets, consider using traditional methods to avoid overhead.

What alternatives do I have to rest and spread operators?

You can use methods like Array.prototype.concat() for arrays or Object.assign() for objects to merge data without creating copies.
