+ * @param arr - The array from which elements will be removed.
+ * @param indicesToRemove - An array of indices specifying the positions of elements to remove.
+ * @returns 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]
+ * console.log(numbers); // [10, 30]
