/**
* Returns the last element of an array.
*
* This function takes an array and returns the last element of the array.
* If the array is empty, the function returns `undefined`.
*
* Unlike some implementations, this function is optimized for performance
* by directly accessing the last index of the array.
*
* @template T - The type of elements in the array.
* @param arr - The array from which to get the last element.
* @returns The last element of the array, or `undefined` if the array is empty.
*
* @example
* const arr = [1, 2, 3];
* const lastElement = last(arr);
* // lastElement will be 3
*
* const emptyArr: number[] = [];
* const noElement = last(emptyArr);
* // noElement will be undefined
