import VolatileMap from 'volatile-map';
const cache = new VolatileMap(3000); // Values expire after 3 seconds
cache.set('foo', 'bar');
cache.set('baz', 'qux', 5000);
console.log(cache.get('foo'));
// => 'bar'
console.log(cache.get('baz'));
// => 'qux'
setTimeout(function () {
console.log(cache.get('foo'));
// => undefined
console.log(cache.get('baz'));
// => 'qux'
}, 4000);

Constructor.
#### ttl
Type: Number
Time to live of the values and keys of the map, after that time, keys and values are deleted.
#### VolatileMap.set(key, value[, ttl])
This method behaves the same as the ES6 Map.set() method, but adds an extra optional argument ttl that allows to set a specific time to live to each key. By default uses the ttl supplied when constructing the object.
#### Other methods
See the ES6 Map object documentation to see all the methods.
