es-toolkit/dist/fp/array/xorWith.d.mts

A state-of-the-art, high-performance JavaScript utility library with a small bundle size and strong type annotations.

//#region src/fp/array/xorWith.d.ts
/**
 * Creates a function that returns the symmetric difference using a custom equality function.
 *
 * The equality function decides whether two values represent the same item, matching the
 * main {@link xorWith} behavior.
 *
 * @template T - The type of elements in the arrays.
 * @param secondArray - Values to compare with the piped array.
 * @param areItemsEqual - Returns true when two values are equal.
 * @returns A function that maps a readonly array to its symmetric difference.
 *
 * @example
 * import { pipe, xorWith } from 'es-toolkit/fp';
 *
 * pipe([{ id: 1 }, { id: 2 }], xorWith([{ id: 2 }, { id: 3 }], (a, b) => a.id === b.id));
 * // => [{ id: 1 }, { id: 3 }]
