* Unzips an array of arrays, applying an `iteratee` function to regrouped elements.

|
|
* If the array is `null` or `undefined`, returns an empty array.

* @template T
|
||
|
|
* @param {T[][] | ArrayLike<ArrayLike<T>> | null | undefined} array - The nested array to unzip. This is an array of arrays,
|
||
|
|
* where each inner array contains elements to be unzipped.
|
||
|
|
* @param {(...args: any[]) => unknown} iteratee - A function to transform the unzipped elements.
|
||
|
|
* @returns {any[]} A new array of unzipped and transformed elements.

|
* @example
|

|
|
* const nestedArray = [[1, 2], [3, 4], [5, 6]];

* const result = unzipWith(nestedArray, (a, b) => a + b);
