javascript - ES6 Proxy Polyfill for IE11

Question

IE11 does not and will not implement ES2015 Proxy objects. Yet IE11's end of extended support is October 14, 2025.

Is there any way to polyfill Proxy objects for IE11? All other browsers support Proxy already.

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...

Edit: I'm asking specifically for IE11 as I know IE to usually have IE specific features that I'm often not aware of.

Edit2: I'm particularly interested in being able to implement a catch-all interceptor. Similar to __getattr__ in Python. It only has to work in IE11.

Best you can get is github: GoogleChrome/proxy-polyfill

According to Babel docs:

Due to the limitations of ES5, Proxies cannot be transpiled or polyfilled.
