Function last

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.

const arr = [1, 2, 3];
const lastElement = last(arr);
// lastElement will be 3

const emptyArr: number[] = [];
const noElement = last(emptyArr);
// noElement will be undefined
