Question

If we slice() an Array and add a new element to either Array, do the changes propagate?

A. Changes made to the original array will automatically propagate to the sliced copy.
B. Changes made to the sliced copy will automatically propagate to the original array.
C. Slicing an array creates a deep copy of the elements, making them independent of the original array.
D. Both the original array and the sliced copy will always remain identical after any modifications.

Answer 1

When using the slice() method on an array, changes do not automatically propagate to the other array. Slicing creates a shallow copy of the elements.

Step-by-step explanation:

When we use the slice() method on an array and add a new element to either the original array or the sliced copy, the changes do not propagate automatically to the other array. Slicing an array creates a shallow copy of the elements, meaning that the original array and the sliced copy share the same elements. However, if we modify one of the shared elements, the change will be reflected in both arrays. To create an independent copy of the elements, we need to make a deep copy of the array.
