Was just wondering why this: var foo = bar = bar && bar.length && bar || (bar = $('#bar')).length ? bar : $('<div />', { id: 'bar' }); was not just this: var foo = bar = bar || (bar = $('#bar')).length ? bar : $('<div />', { id: 'bar' }); Am I missing something?

Keeping an eye out for the part 2 Mon, 21 Nov 2011 22:12:20 +0000http://addyosmani.com/blog/building-mobile-javascript-webapps-with-backbone-js-jquery-part-i/#IDComment225361406 Addyhttp://addyosmani.com/blog/exploring-javascripts-logical-or-operator/#IDComment225279080Thanks! Fixing now. I think an update must have broken it.

Very informative and interesting... The second-to-last code snippet seems to have broken, though. The site displays it as 2 snippets, when I guess they're meant to be one?

My preferred pattern would be something like this : var myApp=(function(){ var MyApp = function () { var that=this; // this is the constructor $(function () { that.init(); }); }; MyApp.prototype = { constructor: MyApp, init: function () { console.log('init called'); } } return MyApp; })(); new myApp(); That reminds me more of a real Class .. in a way :) Thanks for the great post again, Ady Sun, 20 Nov 2011 22:24:36 +0000http://addyosmani.com/blog/essential-js-namespacing/#IDComment224910785 @pomehhttp://addyosmani.com/blog/exploring-javascripts-logical-or-operator/#IDComment224908925Thanks for this article :) This technique is also useful with the RegExp.exec method. Look at this: var expr = /(w+).com/, str = "addyosmani.com", parts = expr.exec( str ) || [ "", "default value" ], domainName = parts[ 1 ]; if( domainName ) { // ... } This'll execute the regular expression "expr" over the string "str". In case it match, exec method will return an array containing the full string and the match part (2 length array). In case it fails, it will returns null; the OR operator is useful now, allowing us to return a default array of values (2 length too). Then, in every case, we're using that array and we're getting the element which index is 1. The good part here is that the "parts" variable will always be an array. If we remove the OR trick, then it may return null in some case, and then the parts[1] could throw an error like "TypeError: Cannot read property '1' of null". Hope you'll like it :) Sun, 20 Nov 2011 22:19:46 +0000http://addyosmani.com/blog/exploring-javascripts-logical-or-operator/#IDComment224908925 Zachttp://addyosmani.com/blog/building-mobile-javascript-webapps-with-backbone-js-jquery-part-i/#IDComment224565867I would LOVE to see part 2 of this article!

If a===0, it'll get changed to 5 here.

Caus i like to know how to do that :-) Fri, 18 Nov 2011 10:11:08 +0000http://addyosmani.com/blog/jqueryuicoverflow/#IDComment223821143 Raymondhttp://addyosmani.com/blog/jqueryuicoverflow/#IDComment223813083Hi! I have the same issue. I would like to adjust the starting point of the coverflow. Did you find out how? Caus i would like to know :). Or have you found an alternative? Thanks!

Perhaps because so many people are using it - so it's impossible to wrap jQuery into define function as this would force everyone into using AMD loaders. So pollution is still there. It probably be better to create alternative jQuery file that's packaged fully as AMD module. Another problem is - as of now define() in jQuery called prior to the file end, so not all functionality of jQuery will be loaded by that moment which will lead to errors. I think there is a bug report for this already. IMHO - jquery AMD implementation as of now is half-arsed.

I have a short question: is it possible to monkey patch a dependency somehow ? With Object Literal it is quite easy to override the default behavior of a method thru the prototype but with AMD the dependencies come as function arguments and I'm not sure whether it is still possible.
