+ * Creates a function that removes a number of values from the end of an array.
+ *
+ * The returned function follows the main {@link dropRight} 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 drop from the end.
+ * @returns A function that maps a readonly array to the remaining prefix.
+ *
+ * @example
+ * import { dropRight, pipe } from 'es-toolkit/fp';
+ *
+ * pipe([1, 2, 3, 4], dropRight(2));
+ * // => [1, 2]
