    zipWith (Functional Programming) es-toolkit

    Creates a function that combines values from arrays by index. Use it with pipe.

    const result = pipe(array, zipWith(...arrs, combine));
    Info

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

    Usage

    zipWith passes values at the same index from the piped array and configured arrays to combine. If arrays have different lengths, missing values are passed as undefined.

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

pipe(
  [1, 2],
  zipWith([10, 20], (a, b) => a + b)
); // => [11, 22]

pipe(
  [1, 2, 3],
  zipWith([10], (a, b = 0) => a + b)
); // => [11, 2, 3]

    Parameters

    arrsArray<readonly unknown[]>required

    The arrays to combine with the piped array.

    combine(...values: unknown[]) => Rrequired

    The function that receives values at the same index, followed by the index, and returns a new value.

    Returns

    A function that maps the piped array to combined values.

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