+/**
+* Creates a function that keeps values whose mapped identity appears in another array.
+*
+* The mapper is applied to values from both arrays. The returned function is
+* lazy-capable inside {@link pipe}.
+*
+* @template T - The type of elements in the piped array.
+* @template U - The type of elements in the configured array.
+* @param secondArray - Values to intersect with the piped array after mapping.
+* @param mapper - Maps values from both arrays to comparison keys.
+* @returns A function that maps the piped array to its mapped intersection.
+*
+* @example
+* import { intersectionBy, pipe } from 'es-toolkit/fp';
+*
+* pipe([{ id: 1 }, { id: 2 }], intersectionBy([2], value => typeof value === 'number' ? value : value.id));
+* // => [{ id: 2 }]
