# WeakSet [![Build Status](https://travis-ci.com/ungap/essential-weakset.svg?branch=master)](https://travis-ci.com/ungap/essential-weakset) [![Coverage Status](https://coveralls.io/repos/github/ungap/essential-weakset/badge.svg?branch=master)](https://coveralls.io/github/ungap/essential-weakset?branch=master) [![Greenkeeper badge](https://badges.greenkeeper.io/ungap/essential-weakset.svg)](https://greenkeeper.io/) ![WebReflection status](https://offline.report/status/webreflection.svg) An essential WeakSet poorlyfill legacy browsers that don't have even a WeakMap but need just a [WeakSet](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakSet). * CDN via https://unpkg.com/@ungap/essential-weakset * ESM via `import WeakSet from '@ungap/essential-weakset'` * CJS via `const WeakSet = require('@ungap/essential-weakset')` Compatible down to IE9, works well with ES5 shim upfront in IE8 (and maybe lower too).
