+ * Creates a function that removes duplicate values using a custom equality function.
+ *
+ * The first value in each equality group is preserved. The returned function is
+ * lazy-capable inside {@link pipe}.
+ *
+ * @template T - The type of elements in the array.
+ * @param areItemsEqual - Returns true when two values should be treated as equal.
+ * @returns A function that maps the piped array to unique values.
+ *
+ * @example
+ * import { pipe, uniqWith } from 'es-toolkit/fp';
+ *
+ * pipe([{ id: 1 }, { id: 1 }, { id: 2 }], uniqWith((a, b) => a.id === b.id));
+ * // => [{ id: 1 }, { id: 2 }]
