Module it-filter

Example

import all from 'it-all'
import filter from 'it-filter'

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

const fn = (val, index) => val > 2 // Return boolean to keep item

const arr = all(filter(values, fn))

console.info(arr) // 3, 4
Copy

Async sources and filter functions must be awaited:

import all from 'it-all'
import filter from 'it-filter'

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

const fn = async val => (val, index) > 2 // Return boolean or promise of boolean to keep item

const arr = await all(filter(values, fn))

console.info(arr) // 3, 4
Copy
