What are the different methods for cloning arrays in JavaScript and their performance?

What are the different methods for cloning arrays in JavaScript?

In JavaScript, common methods for cloning arrays include the spread operator, Array.from(), and slice().

Can you explain the performance differences between these methods?

Sure! The spread operator is generally fast and concise, while Array.from() and slice() can be slightly slower due to additional overhead.

Are there any scenarios where one method is preferred over the others?

Yes, if you need a shallow copy, the spread operator is often preferred for its readability. For deep cloning, consider using JSON methods or libraries.

What about performance in large arrays?

For large arrays, the spread operator and slice() may perform better, but it's best to benchmark in your specific use case.
