Function reduce

reduce<T, U>(
    xs: readonly T[],
    initial: U,
    fn: (acc: U, x: T, i: number) => U,
): U
Fold elements left-to-right into a single accumulated value starting from initial.

Dual API — works data-first or curried for use in pipe.
Type Parameters
- T
- U
Parameters
- xs: readonly T[]
- initial: U
- fn: (acc: U, x: T, i: number) => U
Returns U

    orders,
    Arrays.reduce(0, (total, o) => total + o.price),
  )
```
