+* 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

+*
+* @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.

+* import { intersection, pipe } from 'es-toolkit/fp';
+*
+* pipe([1, 2, 3], intersection([2, 4]));
+* // => [2]
