## README

# WeakSet

[![Build Status](https://travis-ci.com/ungap/weakset.svg?branch=master)](https://travis-ci.com/ungap/weakset) [![Coverage Status](https://coveralls.io/repos/github/ungap/weakset/badge.svg?branch=master)](https://coveralls.io/github/ungap/weakset?branch=master) [![Greenkeeper badge](https://badges.greenkeeper.io/ungap/weakset.svg)](https://greenkeeper.io/) ![WebReflection status](https://offline.report/status/webreflection.svg)

A polyfill for IE11 or browsers that have a WeakMap, but not a [WeakSet](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakSet).

  * CDN via https://unpkg.com/@ungap/weakset
  * ESM via `import WeakSet from '@ungap/weakset'`
  * CJS via `const WeakSet = require('@ungap/weakset')`

Compatible down to IE9, works well with ES5 shim upfront in IE8 (and maybe lower too).
