prray/test/findIndexAsync.test.ts

'Promisified' Array, comes with async method supports(such as mapAsync). And it is compatible with normal array.

import test from 'ava'
import { prray } from '../src/prray'

const p1 = prray([1, 2, 3])
const p2 = prray([0, 2])

const pp1 = toPrrayPromise([1, 2, 3])
const pp2 = toPrrayPromise([0, 2])
