First example could be simpler with reduce, I mean, if you use n as variable in the for version, why not using n in the reduce one?
const array = [1, 2, 3, 4]; const sum = array.reduce((a, n) => a + n, 0);
Actually, this is better as you can extract the reducer part (a, n) => a + n as a function. The other way is not reusable.
(a, n) => a + n
