Expected or Desired Behavior

Open workbench for local testing in IE11 since some customer still uses this browser.

Observed Behavior

Currently, the workbench cannot be opened because of the following error message on the console.

The problem comes from a for loop where a const instead of let or var was used:

While other browsers ignore that IE11 show a more strict behaviour and avoid to init.

Steps to Reproduce

Create a new project, gulp serve, open Workbench in IE11.

Not working in new SPFx 1.7.0 too.

[s-KaiNet]

Any ETA for the fix? Some big companies still use IE11 and even have it in the list of supported corporate browsers.

[andrewconnell]

Is this limited to just the workbench, or SPFx in general?

[SeanCMrsh]

This is happening to me also (IE11 - WB1.7.1) only seems to happen on workbench - I've added pnp polyfills as suggested by some sites but with no joy.
Any ideas

npm install --save @pnp/polyfill-ie11

(index.d.ts in polyfill dir)
import "core-js/es6/array";
import "core-js/modules/es6.promise";
import "core-js/modules/es6.array.iterator.js";
import "core-js/modules/es6.array.from.js";
import "core-js/modules/es6.array.fill.js";
import "core-js/modules/es6.array.find";
import "es6-map/implement";
import "whatwg-fetch";

Please refer to the recently published IE11 support doc here: https://support.office.com/en-us/article/Which-Browsers-Work-With-Office-Online-AD1303E0-A318-47AA-B409-D3A5EB44E452

After reviewing the above doc, can you please verify the issue is still present in the lastest SPFx version (1.8.2)?

const manifests = spfxWindow.debugManifests.getManifests();
const manifestIds = [];
for (const manifest of manifests) {
manifestIds.push(manifest.id.toUpperCase());
}

SCRIPT1053: "const" muss initialisiert sein.

Can someone post a fix for this. I am still having issues and the links posted do not say how to fix it.

Closing issue due no response from original author. If this issue is still occurring, please open a new issue with additional details. Notice that if you have included another related issue as additional comment on this, please open that also as separate issue, so that we can track it independently.

Thanks for raising the concern. Yes, we're aware of this issue. It is a browser compatibility issue and the fix will take more effort than required. Also, this is developer only scenario and not a end user scenario. Here are some of the workarounds you can try:

1. Use any other browser for this scenario?
2. Use hosted workbench

I'm closing the issue.

Thanks for understanding,
Sri
