ES6 Proxy Polyfill  Version

This is a polyfill for ES6 Proxy, supports IE6+ , Node.js, etc.

So far, it supports more features than the proxy-polyfill of GoogleChrome.

The polyfill supports just a limited number of proxy 'trap':

  • get
  • set
  • apply
  • construct

The Proxy.revocable method is also supported, but only for calls to the above traps.

  1. Browser:
    <!--[if lte IE 8]>

    <script type="text/javascript">
