    unzipWith (Functional Programming) es-toolkit

    Creates a function that regroups zipped arrays and combines each position. Use it with pipe.

    const result = pipe(array, unzipWith(iteratee));
    Info

    Prefer the original es-toolkit unzipWith in ordinary code. Use this fp variant when composing transformations with pipe.

    Usage

    unzipWith collects values at the same position from grouped rows, calls iteratee with those values, and returns the results.

    import { pipe, unzipWith } from 'es-toolkit/fp';

pipe(
  [
    [1, 10],
    [2, 20],
  ],
  unzipWith((a, b) => a + b)
); // => [3, 30]

    Parameters

    iteratee(...args: T[]) => Rrequired

    The function that combines values from the same position.

    Returns

    A function that maps zipped rows to combined values by position.

    (target: readonly T[][]) => R[]
