Promise.all + map for all iterables
npm install @xen-orchestra/async-map !License  
> Promise.all + map for all iterables
Installation of the npm package:
``
> npm install --save @xen-orchestra/async-map
Similar to Promise.all + Array#map for all iterables: calls iteratee for each item in iterable, and returns a promise of an array containing the awaited result of each calls to iteratee.
It rejects as soon as te first call to iteratee rejects.
`js
import { asyncMap } from '@xen-orchestra/async-map'
const array = await asyncMap(iterable, iteratee, thisArg)
`
It can be used with any iterables (Array, Map, etc.):
`js
const map = new Map()
map.set('foo', 42)
map.set('bar', 3.14)
const array = await asyncMap(map, async function ([key, value]) {
// TODO: do async computation
//
// the map can be accessed via this
})
#### Use with plain objects
Plain objects are not iterable, but you can use Object.keys, Object.values or Object.entries to help:
`js
const object = {
foo: 42,
bar: 3.14,
}
const array = await asyncMap(
Object.entries(object),
async function ([key, value]) {
// TODO: do async computation
//
// the object can be accessed via this because it's been passed as third arg`
},
object
)
Similar to asyncMap but waits for all promises to settle before rejecting.
`js
import { asyncMapSettled } from '@xen-orchestra/async-map'
const array = await asyncMapSettled(iterable, iteratee, thisArg)
