A map generator for iterators.

const map = require('@iterables/map')

const iter = map(function * () {
  yield 1
  yield 2
}(), xs => xs * 2)

console.log([...iter]) // [2, 4]


$ npm install --save @iterables/map


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!
