+ * Creates a function that returns the last count values of an array.
+ *
+ * The returned function follows the main {@link takeRight} behavior and returns a new array.
+ * Use it with {@link pipe}.
+ *
+ * @template T - The type of elements in the array.
+ * @param count - The number of values to take from the end.
+ * @returns A function that maps a readonly array to its suffix.
+ *
+ * @example
+ * import { pipe, takeRight } from 'es-toolkit/fp';
+ *
+ * pipe([1, 2, 3, 4], takeRight(2));
+ * // => [3, 4]
