Returns the first result from an async iterator
npm install it-first
> Returns the first result from an async iterator
Return the first value in an (async)iterable
``javascript
import first from 'it-first'
// This can also be an iterator, generator, etc
const values = [0, 1, 2, 3, 4]
const res = first(values)
console.info(res) // 0
`
Async sources must be awaited:
`javascript
import first from 'it-first'
const values = async function * () {
yield * [0, 1, 2, 3, 4]
}
const res = await first(values())
console.info(res) // 0
`
`console`
$ npm i it-first
