**Note:** Concatenating with the ``+=`` operator will create a new array, which has a cost. If you want to append another array to an existing array, :ref:`append_array<class_Array_method_append_array>` is more efficient.
**Note:** Arrays are always passed by reference. To get a copy of an array which can be modified independently of the original array, use :ref:`duplicate<class_Array_method_duplicate>`.

**Note:** When declaring an array with ``const``, the array itself can still be mutated by defining the values at individual indices or pushing/removing elements. Using ``const`` will only prevent assigning the constant with another value after it was initialized.
