Provide an expiration time, in milliseconds, to the constructor. Expiration times can also be provided for each set call. If there's no expiration time, the entry will never expire.
const ExpiringMap = require('expiring_map').ExpiringMap
let map = new ExpiringMap(3000)
map.set(1, 1) // will expire after 3 seconds
map.set(2, 2, 1000) // will expire after 1 second
let map2 = new ExpiringMap()
map2.set(1, 1) // will never expire
