## Installation

## Usage

```js

import { PromisedMap } from 'promised-map';

const map = new PromisedMap();

// set key/value pair and retrieve related promise.

const promise = map.set('foo', 42);

// resolve promise later by key

map.resolve('foo', 'bar');

// reject promise by key

map.reject('foo', new Error('error'));

// check if promise is still pending

map.has('foo');

// resolve all promises and clear map

map.resolveAll('bar');

// reject all promises and clear map

map.rejectAll(new Error('error'));

// iterate all promises

map.forEach((value, key) => { /* ... */ });

```
