Treat one or more iterables as a single iterable
npm install it-merge
> Treat one or more iterables as a single iterable
Merge several (async)iterables into one, yield values as they arrive.
Nb. sources are iterated over in parallel so the order of emitted items is not guaranteed.
``javascript
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:
`javascript
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
`
`console`
$ npm i it-merge
