 * Retrieves elements from an array at the specified indices.
 *
 * This function supports negative indices, which count from the end of the array.

 * @template T
 * @param {readonly T[]} arr - The array to retrieve elements from.
 * @param {number[]} indices - An array of indices specifying the positions of elements to retrieve.
 * @returns {T[]} A new array containing the elements at the specified indices.
 *
 * @example
 * const numbers = [10, 20, 30, 40, 50];
 * const result = at(numbers, [1, 3, 4]);
 * console.log(result); // [20, 40, 50]
