+* Creates a function that keeps values from the piped array that are also present in another array.
+*
+* Equality follows SameValueZero through Set membership, matching the main
+* {@link intersection} implementation. The returned function is lazy-capable
+* inside {@link pipe}.
+*
+* @template T - The type of elements in the arrays.
+* @param secondArray - Values to intersect with the piped array.
+* @returns A function that maps the piped array to its intersection.
+*
+* @example
+* import { intersection, pipe } from 'es-toolkit/fp';
+*
+* pipe([1, 2, 3], intersection([2, 4]));
+* // => [2]
