Slayer95 / set-clone.js
Created August 5, 2017 17:02
Set shallow clone
const assert = require('assert');
const fs = require('fs');
const vm = require('vm');
const iterateSetElems = set => Set.prototype.keys.call(set);
const Builtin = require('proposal-istypes/polyfill'); // Git dependency
const SetPolyfillSource = fs.readFileSync(require.resolve('es6-shim'), 'utf8');
// Get a good polyfill for Set.
// We achieve this by loading the Set implementation from es6-shim.
