it-take

Stop iteration after n items have been received

About

For when you only want a few values out of an (async)iterable.

Example

import take from 'it-take'
import all from 'it-all'

// This can also be an iterator, generator, etc
const values = [0, 1, 2, 3, 4]

const arr = all(take(values, 2))

console.info(arr) // 0, 1

Async sources must be awaited:

import take from 'it-take'
import all from 'it-all'

const values = async function * () {
  yield * [0, 1, 2, 3, 4]
}

const arr = await all(take(values(), 2))

console.info(arr) // 0, 1
