ES Proposal spec-compliant shim for Set.prototype.symmetricDifference. Invoke its "shim" method to shim
Set.prototype.symmetricDifference 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 symmetricDifference = require('set.prototype.symmetricdifference'); var set1 = new Set([1, 2]); var set2 = new Set([2, 3]); var result = symmetricDifference(set1, set2); assert.deepEqual(result, new Set([1, 3])); symmetricDifference.shim(); var shimmedResult = set1.symmetricDifference(set2); assert.deepEqual(shimmedResult, new Set([1, 3]));
