/**
* 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]
