Everyone seems to be saying the same thing here, except no one has provided a solid 1 liner solution.

So from this answer, https://stackoverflow.com/a/32107845/584147

Which simply says that,

1. Both of these browsers (IE 11 & Edge) use the navigator.appName of "Netscape" (compared to older versions of IE which use "Microsoft Internet Explorer" as the navigator.appName)
2. in IE 11 the navigator.appVersion says 'trident', in Edge the navigator.appVersion does not say trident

I have turned this into a simple 1 liner for anyone else who ends up here and in need of it.

var isieEdge = (navigator.appName == "Netscape") && (navigator.appVersion.indexOf('Trident') === -1); // IE Edge

alert(isieEdge);
