* of elements removed from the end.

* @template T - The type of elements in the array.
* @param arr - The array from which to drop elements.
* @param itemsCount - The number of elements to drop from the end of the array.
* @returns A new array with the specified number of elements removed from the end.
*
* @example
* const array = [1, 2, 3, 4, 5];
* const result = dropRight(array, 2);
* // result will be [1, 2, 3] since the last two elements are dropped.
