Filters the passed iterable by using the filter function
npm install it-filter
> Filters the passed iterable by using the filter function
Filter values out of an (async)iterable
``javascript
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
`
Async sources and filter functions must be awaited:
`javascript
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
`
`console`
$ npm i it-filter
