* Removes elements from an array at specified indices and returns the removed elements.

* @template T

|
* @param {T[]} arr - The array from which elements will be removed.

|
* @param {number[]} indicesToRemove - An array of indices specifying the positions of elements to remove.
|

* @returns {Array<T | undefined>} An array containing the elements that were removed from the original array.

*
|
|
* @example
|
|
* const numbers = [10, 20, 30, 40, 50];
|
|
* const removed = pullAt(numbers, [1, 3, 4]);
|
|
* console.log(removed); // [20, 40, 50]
