+ * of elements removed from the end.
+ *
+ * @template T - The type of elements in the array.
+ * @param collection - The array from which to drop elements.
+ * @param itemsCount - The number of elements to drop from the end of the array.
+ * @param [guard] - Enables use as an iteratee for methods like `_.map`.
+ * @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.
