zip
Combines multiple arrays into a single array of tuples.
This function takes multiple arrays and returns a new array where each element is a tuple containing the corresponding elements from the input arrays. If the input arrays are of different lengths, the resulting array will have the length of the longest input array, with undefined values for missing elements.
Signature
typescript
function zip<T>(arr1: T[]): [T][];
function zip<T, U>(arr1: T[], arr2: U[]): [T, U][];
function zip<T, U, V>(arr1: T[], arr2: U[], arr3: V[]): [T, U, V][];
function zip<T, U, V, W>(arr1: T[], arr2: U[], arr3: V[], arr4: W[]): [T, U, V, W][];
function zip<T>(...arrs: T[][]): T[][];Parameters
...arrs(T[][]): The arrays to zip together.
Returns
(T[][]): A new array of tuples containing the corresponding elements from the input arrays.
Examples
typescript
import { zip } from 'js-utils-es/array';
const arr1 = [1, 2, 3];
const arr2 = ['a', 'b', 'c'];
const result = zip(arr1, arr2);
// result will be [[1, 'a'], [2, 'b'], [3, 'c']]
const arr3 = [true, false];
const result2 = zip(arr1, arr2, arr3);
// result2 will be [[1, 'a', true], [2, 'b', false], [3, 'c', undefined]]
