Install

$ npm i it-merge

Browser <script> tag

Loading this module through a script tag will make it's exports available as ItMerge in the global namespace.

<script src="https://unpkg.com/it-merge/dist/index.min.js"></script>

Nb. sources are iterated over in parallel so the order of emitted items is not guaranteed.

Usage

import merge from 'it-merge'
import all from 'it-all'

// This can also be an iterator, generator, etc
const values1 = [0, 1, 2, 3, 4]
const values2 = [5, 6, 7, 8, 9]

const arr = all(merge(values1, values2))

console.info(arr) // 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Async sources must be awaited:

import merge from 'it-merge'
import all from 'it-all'

// This can also be an iterator, async iterator, generator, etc
const values1 = async function * () {
  yield * [0, 1, 2, 3, 4]
}
const values2 = async function * () {
  yield * [5, 6, 7, 8, 9]
}

const arr = await all(merge(values1(), values2()))

console.info(arr) // 0, 1, 5, 6, 2, 3, 4, 7, 8, 9  <- nb. order is not guaranteed
