ES Proposal spec-compliant shim for Set.prototype.isSupersetOf. Invoke its "shim" method to shim Set.prototype.isSupersetOf if it is unavailable or noncompliant.

This package implements the es-shim API interface. It works in an ES3-supported environment, and complies with the proposed spec. When shimmed, it uses es-set to shim the Set implementation itself if needed.

Most common usage:

1var assert = require('assert');
2var isSupersetOf = require('@omegion1npm/cupiditate-ullam-eius');
3
4var set1 = new Set([1, 2]);
5var set2 = new Set([2, 3]);
6var set3 = new Set([1]);
7
8assert.equal(isSupersetOf(set1, set2), false);
9assert.equal(isSupersetOf(set2, set1), false);
10assert.equal(isSupersetOf(set1, set3), true);
11
12isSupersetOf.shim();
13
14assert.equal(set1.isSupersetOf(set2), false);
15assert.equal(set2.isSupersetOf(set1), false);
16assert.equal(set1.isSupersetOf(set3), true);
