#Four Ways To Do Pub/Sub With jQuery and jQuery UI (in the future)

Between jQuery 1.7 and some of work going into future versions of jQuery UI, there are a ton of hot new ways for you to get your publish/subscribe on. Here are just four of them, three of which are new.

(PS: If you're unfamiliar with pub/sub, read the guide to it that Julian Aubourg and I wrote here http://msdn.microsoft.com/en-us/scriptjunkie/hh201955.aspx)

##Option 1: Using jQuery 1.7's $.Callbacks() feature:

$.Callbacks are a multi-purpose callbacks list object which can be used as a base layer to build new functionality including simple publish/subscribe systems. We haven't yet released the API documentation for this feature just yet, but for more information on it (including lots of examples), see my post on $.Callbacks() here:

// Note that this uses my Pub/Sub implementation, which is slightly different than

Incorrect ES5 fallbacks

Over the weekend I implemented a few Array methods in plain JavaScript to avoid recently patched Rhino bugs. That got my thinking about ES5 fallback implementations in various JavaScript libs/frameworks/transpilers. I decided to compile a not-so-complete list of ES5 related discrepancies found in many of them. Differences in native vs. fallback implementations create cross-browser inconsistencies and increase the chance of usage errors. I hope this post will raise awareness of just how hard it is to follow spec (during my research I found a couple of issues in my own projects too). All library developers should to take a closer look at their code and make the small changes needed to follow the specification (especially if your code forks for native methods).

Common Issues

Most implementations suffer from the foll
