API

reduce(iterable, fn[, initial]) -> Value

• iterable: any Iterator — a generator instance, Array, Map, String, or Set
• fn: A function taking acc, xs, idx, and all and returning any value.
  • acc: the accumulator returned by fn. The first value is the first item from the iterable if initial is not given.
  • xs: an item from iterable.
  • idx: a number reflecting the index of the current item.
  • all: the full iterable object.

Returns a value representing the reduction of the input iterator.
