xor (Functional Programming) ​
Creates a function that returns values that appear in exactly one of two arrays. Use it with pipe.
typescript
const result = pipe(array, xor(secondArray));INFO
Prefer the original es-toolkit xor in ordinary code. Use this fp variant when composing transformations with pipe.
Usage ​
xor returns the symmetric difference of the piped array and secondArray, without duplicate values.
typescript
import { pipe, xor } from 'es-toolkit/fp';
pipe([1, 2, 3], xor([2, 3, 4])); // => [1, 4]Parameters ​
secondArray(readonly T[]): The array to compare with the piped array.
Returns ​
((array: readonly T[]) => T[]): A function that maps a readonly T[] to the symmetric difference.
