Suppose if I had the following array:
even_numbers = Int32[2,4,6,8,10] # Creating a 5 element array.
and I made a shallow copy:
b = copy(even_numbers)
If I were to modify or delete an element from b why doesn’t it reflect on even_numbers?
deleteat!(b, 2) # the element of 4 should be removed.
If I were to display even_numbers, 4 still exists.
5-element Array{Int32,1}:
2
4
6
8
10
I always thought if you modify a shallow copy of a collection it will also modify the original collection. If you didn’t want to modify the original, you can use deepcopy()
