A very small subset of ES6 Map that is good enough for small collections
npm install mini-mapThe mini map implements a subset of the ECMAScript 6 Map that performs well
enough for very small collections.
This implementation exists for a good-enough approximation of a Map that doesn't
waste much space even if an alternative is almost always used in practice.
Keys may be objects.
Supports has, get, set, delete, and clear.
The MiniMap constructor supports no arguments.
``js``
var map = new Map();
var key = {};
expect(map.has(key)).toBe(false);
map.set(key, 10);
expect(map.get(key)).toBe(10);
expect(map.has(key)).toBe(true);
map.delete(key);
expect(map.has(key)).toBe(false);
map.clear();
