Map.fromObject and Map.prototype.toObject

BetterJS provide a easy way to convert data between maps and objects. That's Map.fromObject and Map.prototype.toObject.

Objects can use a string or symbol as a key, and only string key can be enumerable. So Map.fromObject only takes entries with string keys. Maps can use anything as a key, for the same reason, Map.prototype.toObject only takes string key too. It's must be mentioned that the number or bigint keys will be ignored rather then convert to string.

Usage

import 'https://better-js.fenz.land/src/map-and-set/map-from-and-to-object.js';

const map= Map.fromObject( { 'foo':'bar', }, );

const object= map.toObject();
