How to target Edge browser with javascript

Question

I know you should do feature detection where possible, but can you detect in Javascript if the browser is the Microsoft Edge browser?

Try to detect features instead of a specific browser. It's more future-proof. Only rarely should you use browser detection.

With that out of the way: one option is to use a library (there are many intricacies to User Agent strings), or alternatively to parse window.navigator.userAgent manually.

Using a parser library

# https://github.com/faisalman/ua-parser-js.

var parser = new UAParser();
var result = parser.getResult();

var name = result.browser.name;
var version = result.browser.version;

Raw approach with Javascript

# Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) \
# Chrome/42.0.2311.135 Safari/537.36 Edge/12.10136

window.navigator.userAgent.indexOf("Edge") > -1
