// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
// ie === undefined
// If you're in IE (>=5) then you can determine which version:
// ie === 7; // IE7
// Thus, to detect IE:
// if (ie) {}

Luhn10 algorithm

Implementation of the Luhn 10 algorithm to check validity of credit card numbers. See http://en.wikipedia.org/wiki/Luhn_algorithm for details on the algorithm.

var validCreditCard = function(a,b,c,d,e){for(d=+a[b=a.length-1],e=0;b--;)c=+a[b],d+=++e%2?2*c%10+(c>4):c;return!(d%10)};

validCreditCard('378282246310005'); //=> true
validCreditCard('378282246310006'); //=> false

// some numbers to test with
// 378282246310005 371449635398431 378734493671000

Here’s an example of my current web app user agent, device, and/or feature detection approach. I tend to inline this in the page header just before the stylesheet as part of the distribution build. A benefit of this approach is that detection is done early without any external dependencies. It’s also straightforward to modify or extend while you…
env = (function() {
var flags = {}, ua = navigator.userAgent, el = document.createElement('div'), video = document.createElement('video'), audio = document.createElement('audio'), root = document.documentElement, i
function flag(names) {
names = names.split(' ')
for (i = 0; i < names.length; i++)
flags[names[i]] = true
}
function classnames() {
var names = [], name
for(name in flags) if (flags.hasOwnProperty(name))
