title: ES6 Proxy Polyfill for IE11
body: <p>IE11 does not and will not implement ES2015 Proxy objects. Yet IE11's end of extended support is October 14, 2025.</p>
  
  <p>Is there any way to polyfill Proxy objects for IE11? All other browsers support Proxy already.</p>
  
  <p>If yes then we would all be able to use it in production today. If not then we'll have to wait almost a decade...</p>
  
  <p>Edit: I'm asking specifically for IE11 as I know IE to usually have IE specific features that I'm often not aware of.</p>
  
  <p>Edit2: I'm particularly interested in being able to implement a catch-all interceptor. Similar to <code>__getattr__</code> in Python. It only has to work in IE11.</p>
