Zone JS problem with Edge

[debanjanbasu]

I am using the latest EDGE browser, and this is the error I am getting, while loading Zone js

Can confirm. Using latest Edge version (Microsoft EdgeHTML 14.14393). Couldn't reproduce neither in Chrome latest or IE11; it runs just fine both there.

It seems Edge doesn't like calling global['fetch']() (zone.js, line 556) without an argument and ends the script abruptly.

Yes, this is a weird error, how come the earlier Zone JS worked perfectly? This is a strange error.

+1 on this issue. Works fine in Chrome. I get the same error as above in Edge. Also odd that it works fine in Edge if I reference the Zone.js file like this.

<script src="https://unpkg.com/zone.js@0.6.17?main=browser"></script>

However, anything over 6.17 breaks in Edge

I can confirm that it breaks in Microsoft EdgeHTML 14.393. I modified my local source code repository to
global['fetch']('') and everything now works fine. That seems like a decent workaround/fix to the 44c46fa commit that added this breaking change.

zone.js/dist/zone.js

Line 550 in 44c46fa

var fetchPromise = global['fetch']();

You are right wizarrc, your fix does indeed solve the issue. It is actually right, as EDGE is following very strict checking of es6 features.
