IE.JS

Making Internet Explorer detection as simple as possible via global IE variable.

Sample Usage

1. Simply detect IE

    if (IE) {
      console.log("You're using Internet Explorer");
    }

2. Compare IE version

    if (IE < 8) {
      console.log("You're using outdated Internet Explorer. Please upgrade your browser");
    } else {
      console.log("Modern browser (including IE8+) is used!");
    }

3. Check exact IE version

    // Correct
    if (IE && IE == 8) {
      console.log("You're using Internet Explorer 8!");
    }

    // Incorrect. This won't work. Details to be found in "Limitations" section below.
    if (IE && IE === 8) {
      console.log("You're using Internet Explorer 8!");
    }

global.IE variable might be an object (if Internet explorer is used) or undefined in case you're using modern, non-ie browsers.

Limitations

You can't use === in oder to detect IE version, == must be used. More details to be found here: http://sidekicksrc.com/post/the-value-of-valueof/
