How do I detect IE10 using javascript?

Question

As many already posted in other questions (also in jQuery documentation), the old jQuery.browser.version is deprecated and works only in jquery1.3.

In general it's a bad idea to check for browser version, it's considered a better practice to check for browser features. But if you're sure what you're doing:

function getIEVersion(){
    var agent = navigator.userAgent;
    var reg = /MSIE\s?(\d+)(?:\.(\d+))?/i;
    var matches = agent.match(reg);
    if (matches != null) {
        return { major: matches[1], minor: matches[2] };
    }
    return { major: "-1", minor: "-1" };
}

var ie_version =  getIEVersion();
var is_ie10 = ie_version.major == 10;

We have the following code in production, so it works and well-tested.

And yes, we did have a need to detect IE10, not just a particular feature that exists in IE10 but not in earlier versions.
