I need a reliable way to detect the Edge browser (including the pre-chromium Edge if possible) from a web page. User Agent String is no use because it can be impersonated. There is much talk of using "feature detection" for that but I am not finding
any concrete example. Can anyone please help? Thanks.
Since Edge uses JScript instead of JavaScript. A detection for the existence of JScript would eliminate non-Microsoft browsers. After that, the User Agent String then becomes usable for my purpose. How can I detect JScript?
