> Automatically cleanup expired items in a Map
## Install
```
$ npm install map-age-cleaner
```
## Usage
```js
import mapAgeCleaner from 'map-age-cleaner';
const map = new Map([
['unicorn', {data: '🦄', maxAge: Date.now() + 1000}]
]);
mapAgeCleaner(map);
map.has('unicorn');
//=> true
// Wait for 1 second...
map.has('unicorn');
//=> false
```
> **Note**: Items have to be ordered ascending based on the expiry property. This means that the item which will be expired first, should be in the first position of the `Map`.
