+/**
+* 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
