What are the different methods for copying arrays and their performance?

What are the different methods for copying arrays in programming?

There are several methods for copying arrays, including shallow copy, deep copy, and using built-in functions like slice or spread operator.

Can you explain the difference between shallow copy and deep copy?

Sure! A shallow copy creates a new array but does not clone nested objects, while a deep copy duplicates everything, including nested objects.

Which method is the most efficient for large arrays?

For large arrays, using the spread operator or Array.from() is often efficient, but performance can vary based on the context and data structure.

Are there any benchmarks available for these methods?

Yes, there are benchmarks available that compare the performance of different array copying methods. They typically show that the spread operator and slice are quite fast.
