/**
|
|
* Combines multiple arrays into a single array using a custom combiner function.
|
|
*
|
|
* This function takes one array and a variable number of additional arrays,
|
|
* applying the provided combiner function to the corresponding elements of each array.
|
|
* 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.
|
|
*
|
|
* @template T - The type of elements in the input arrays.
|
|
* @template R - The type of elements in the resulting array.
|
|
* @param {Array<((...group: T[]) => R) | ArrayLike<T> | null | undefined>} combine - The combiner function that takes corresponding elements from each array and returns a single value.
|
|
* @returns {R[]} A new array where each element is the result of applying the combiner function to the corresponding elements of the input arrays.
|
|
*
|
|
* @example
|
|
* const arr1 = [1, 2, 3];
|
|
* const arr2 = ['a', 'b', 'c'];
|
|
* const result = zipWith(arr1, arr2, (num, char) => `${num}${char}`);
|
|
* // result will be ['1a', '2b', '3c']
