jQuery 1.6 came with a rewrite of the .attr() method and the introduction of the .prop() method. This came with a significant performance benefit and changed the way attributes and properties are treated internally in jQuery. Most of all, it gives the user a chance to finally differentiate between the two. In my talk, I plan to expound on the difference between attributes and properties and the advantages of working with both. I'll focus mainly on a discussion of HTML vs the DOM and how interacting with one can be more beneficial than another in certain use cases.

Do you write JavaScript? Congratulations, you're probably awesome at Node.js! While thinking about things from a server-side perspective might feel off-putting and unnatural, things like callbacks, storing data in JSON, and implementing actual websites probably do not. We'll go beyond getting Node installed and talk about how to quickly build a working web application, and demonstrate that Node can offer frontend developers more than just a new prototyping tool or way of creating endless chat servers.

If you're into asynchronous programming, you'll love jQuery 1.7! Not only do Deferreds gets progress callbacks, but you also get a brand new constructor, $.Callbacks, that covers pretty much any need you may have when it comes to listing and firing callbacks in your application. Sounds too good to be true? Yet another thingy that's impossible to grasp? Fear not: Julian will walk you through it and make you the first persons in the world to know about $.Callbacks in and out!

As your front-end application grows it is important to abstract pieces of your implementation to make it easier to extend and less painful to maintain.

AmplifyJS is a JavaScript library that was developed to assist with a common set of problems in front-end development. The three components consist of a publish and subscribe messaging system, a persistent storage component that abstracts various cross-browser concerns, and a request piece that sets out to make data retrieval more maintainable.

This talk will start with a sample application that is brittle and tightly coupled and we will slowly enhance the application by the three AmplifyJS components. In the end we will have an application that is testable, flexible, and loosely coupled.

In spite of the fact that projects like jQuery set a good example with strong test suites and tooling, an enormous amount of Javascript is either untested (see Most Popular jQuery Plugin list ) or tested using browser automation. The former results in ritual frustration for developers gluing applications together, and the latter a slow and brittle method for software verification.

In this talk John will cover some simple reasons for testing all your Javascript, even the simplest of plugins, in Javascript and address possible cultural reasons for the lack of said testing. He'll then examine some strategies to move more of your testing into the language itself, and finally cover some of the pitfalls you'll encounter when you do.

jQuery plugins are everywhere, and the chance that YOU will write one—if you haven't already—are pretty high. It might start with a little bit of functionality that you want to reuse or share with someone else, but before you know it… you've released dozens of jQuery plugins and you're writing articles and giving presentations on jQuery Plugin Authoring Best Practices at conferences…. Ok, maybe that's just me.

Regardless, there are many techniques you should know for writing your own reusable jQuery code, or "jQuery plugin," in a way that makes it feel like a natural extension of jQuery.

In this talk, you'll learn how to create custom selectors, chainable methods that double as getters and setters, and traversal or filtering methods that are .end()-able. You'll learn how to organize your code in IIFEs and namespaces, extend option defaults, and even create a custom package.json for your plugin, so that it can be submitted to the upcoming jQuery plugins index.

Come and see the future of jQuery Templates, as it moves from Beta1 towards a V1 product. The new jQuery Templates is taking two forms: JsRender – lean and mean, for fast rendering of templates as strings, and JsViews – for powerful interactive browser apps in which Data Link and Templates work hand-in-hand. See how with declarative data linking and templating together, creating powerful data-driven UI is easy, whether using MVVM patterns or binding directly to JSON, and whatever the richness or complexity of the underlying data.

jQuery UI is already building its future data-bound widgets on top of this technology. With JsViews and JsRender integration between jQuery UI controls and your own data and UI becomes trivially straightforward.

With at least 37 A-grade supported environments, debugging your jQuery Mobile application is no easy task. Having been spoiled by Firebug and the developer tools that have followed in its footsteps on desktop browsers, it isn't exactly obvious how to go about this for the Mobile web (e.g., just try to view the rendered source of any page in most mobile browsers). In this talk we'll cover how to cover your bases both in terms of emulators (Android, Blackberry, iOS, Opera Mobile), remote debugging and inspection (Mobile Webkit, Opera Mobile and Mini), and finally online webapps such as Tutti or JSConsole.

In this talk, we'll see how jQuery UI is dealing with this problem as the API is being redesigned for all existing components. We'll discuss how jQuery UI is implementing the changes and how the upgrade process won't force users to undergo a massive all-or-nothing upgrade, allowing them to start using new components immediately while easing into the new APIs.

jQuery is a completely community-driven project, and we're constantly on the lookout for talented and motivated people to help us push forward. In this talk, we'll go over the many facets of the project where you can find a niche and make a meaningful contribution to the ecosystem. We'll also discuss how writing clean, consistent and readable code is fundamental to promoting collaboration, contribution and distributed development, and explain how the team uses the jQuery Core Style Guide to write code that looks like it was written by a single developer.

Whether you're passionate about servers, design, documentation, testing, helping others, or just writing JavaScript, we're sure to have something for you!

jQuery 1.7 has several improvements to both the event API and plumbing. Highlights include:

A new jQuery.fn.on() method that unifies direct and delegated event handling Special event handlers can process trigger data and detect delegated events Improved performance for delegated events The normal quota of IE 6/7/8 bug fixes
