zip (Functional Programming) ​
Creates a function that groups values from arrays by index. Use it with pipe.
typescript
const result = pipe(array, zip(...arrs));INFO
Prefer the original es-toolkit zip in ordinary code. Use this fp variant when composing transformations with pipe.
Usage ​
zip groups the value at each index from the piped array and the configured arrays. If arrays have different lengths, missing values are undefined.
typescript
import { pipe, zip } from 'es-toolkit/fp';
pipe([1, 2], zip(['a', 'b'])); // => [[1, 'a'], [2, 'b']]
pipe([1, 2, 3], zip(['a'])); // => [[1, 'a'], [2, undefined], [3, undefined]]Parameters ​
arrs(Array<readonly T[]>): The arrays to zip with the piped array.
Returns ​
((array: readonly T[]) => T[][]): A function that maps the piped array to grouped rows by index.
