There are 2 types of array cloning: shallow & deep. Shallow copies only cover the 1st level of the array and the rest are referenced. If you want a true copy of nested arrays, you’ll need a deep clone. Shallow copy is a faster and more memory-efficient method for copying objects and arrays. On the other hand, deep copying ensures that your copied objects are completely independent of the original objects.
