ES Proposal spec-compliant shim for Set.prototype.difference. Invoke its "shim" method to shim Set.prototype.difference
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:
var assert = require('assert');
var difference = require('@devtea2025/magnam-molestiae-labore-ex');
var set1 = new Set([1, 2]);
var set2 = new Set([2, 3]);
var result = difference(set1, set2);
assert.deepEqual(result, new Set([1]));
difference.shim();
var shimmedResult = set1.difference(set2);
assert.deepEqual(shimmedResult, new Set([1]));
