Direct Set / Map

This module simply exports Map, WeakMap, Set, and WeakSet extends with either set(key, value) or add(value) that returns the value itself, instead of the map or set.

import {Map, WeakMap, Set, WeakSet} from '@webreflection/dsm';

const obj = {};
console.assert((new Map).set('key', 1) === 1);
console.assert((new WeakMap).set(obj, 2) === 2);
console.assert((new Set).add(3) === 3);
console.assert((new WeakSet).add(obj) === obj);
