map-age-cleaner

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 ```
