@matthewDDennis what is the version of ng2 that you've got in your setup? Could you please share with us what you've got in File: angular2.dev.js, Line: 4030, Column: 5 on your machine?

[matthewDDennis]

Checked on my Win10 machine and it works on Edge.

Found the issue. I had to add es6-shim.js before system.js. Strange, as I thought this was incorporated into system.js.

[pkozlowski-opensource]

Nope, system.js has only very minimal polyfill for ES5 things like Array.indexOf - if you want to run your code in a browser that doesn't support ES6 (like IE11) you need es6 polyfill (es6-shim.js is one of them)

[johnpapa]

yep. you need es6-shim for that.
