API

map(iterable, fn) -> Iterator

• iterable: any Iterator — a generator instance, Array, Map, String, or Set
• fn: A function taking xs, idx, and all and returning any value.
  • xs: an item from iterable.
  • idx: a number reflecting the index of the current item.
  • all: the full iterable object.

Returns a mapped iterator. Pretty standard stuff!
