Symbol and Proxy is not defined in IE11

[jackylee941130]

I have added import 'proxy-polyfill/proxy.min.js' import 'core-js/stable' import 'regenerator-runtime/runtime' to my worker file.

However, it does not work properly and still get two error messages in IE11: Symbol is not defined. Proxy is not defined.

Could anyone provide a working example for IE11? Thanks.

You need to import those polyfills in both your main thread code and your worker.
