/**

|
* Unzips an array of arrays, applying an `iteratee` function to regrouped elements.
|
||
|
|
*
|
||
|
|
* @template T, R
|
||
|
|
* @param {T[][]} target - The nested array to unzip. This is an array of arrays,
|
||
|
|
* where each inner array contains elements to be unzipped.
|
||
|
|
* @param {(...args: T[]) => R} iteratee - A function to transform the unzipped elements.
|
||
|
|
* @returns {R[]} A new array of unzipped and transformed elements.
|

|
|
*
|
||
|
|
* @example
|
||
|
|
* const nestedArray = [[1, 2], [3, 4], [5, 6]];
|
||
|
|
* const result = unzipWith(nestedArray, (item, item2, item3) => item + item2 + item3);
|
||
|
|
* // result will be [9, 12]
