Automatically cleanup expired items in a Map

$ npm install map-age-cleaner

import mapAgeCleaner = require('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
