A simple map implementation that supports multiple keys.
> multikey-map uses mixed-map internally, which is a map implementation that uses both Map and WeakMap internally.
``sh`
npm install multikey-map
`ts
import MultikeyMap from 'multikey-map';
let map = new MultikeyMap<[string, number], string | undefined>();
map.set(['foo', 0], 'a');
map.set(['foo', 1], 'b');
map.get(['foo', 0]); // 'a'
map.get(['foo', 1]); // 'b'
map.get(['foo', 2]); // undefined
map.has(['foo', 2]); // false
map.hasAndGet(['foo', 2]); // [false, undefined]
map.set(['bar', 0], undefined);
map.get(['bar', 0]); // undefined
map.has(['bar', 0]); // true
map.hasAndGet(['bar', 0]); // [true, undefined]
