Bowser

A Browser detector. Because sometimes, there is no other way, and not even good modern browsers always provide good feature detection mechanisms.

So... it works like this:

if (bowser.msie && bowser.version <= 6) {
  alert('Hello China');
}

browser = require('bowser').browser; becomes browser = require('bowser');
