I suggest you ...

Office Add-ins should run in Edge, not IE11

At the moment Word runs Add-ins in IE11

IE11 doesnt support ES2016, and is therefore much harder to develop for than all of the other newer browsers (Safari, Chrome, Edge).

Word should run Add-ins in Edge

        I'm really frustrated now, nearly all libraries are using ES2016 nowadays…..

        Office Developer Team, can you please provide any kind of ETA as to when we might be able to begin use of Edge-based renderer and ECMAScript 6 instead of Internet Explorer 11 with new Office.js JavaScript-based Office add-ins?

        There was just a major news article released where Microsoft calls IE "a compatibility solution, not a browser" (https://www.theverge.com/2019/2/8/18216767/microsoft-internet-explorer-warning-compatibility-solution), making this IMO even further a priority that Microsoft itself also moves away from it for its own internals, and removes the requirement that new development (like with Office JavaScript-based Add-ins) target IE11 exclusively.

        Edge replaced IE11 4 years ago, and IE11 lacks EC16 support, even for basics like classes, meaning the new Office.js lacks support for clean object-oriented programming (short of transpiling from TypeScript), as well as other ECMAScript 2015 features, and basics like variables in CSS. Considering that, I believe this will be a really helpful enhancement.

        Thanks,
        Dan

        Considering that many organisations still run Windows 7 and Edge is not supported in Windows 7, will these clients still run Office Add-ins in IE11? If so - would a better approach to this issue be to embed a better browser engine in Office so that everyone will have the same experience and the developers won't have to jump through the same old IE hoops?

        Outlook Apps has frontend limitations because of ES6+ on IE11. it would be much better to switch to Edge.

        Additionally Save as web also should considering save for Edge HTML 5 above IE 6 and above

        Versions of webpack-dev-server after 2.7.1 don't support IE11, so switching from IE11 to Edge will help developers using common build tools like @angular/cli. Please prioritize this!

        Thats great! If I could just add an extra suggestion for awesomeness: make sure that edge's "developer tools/js debugger" is available when running add-ins in Word
