According to the authors, doing this with _javascript_ requires painful code forking. That name, unknown but treasured, is someplace in Ada's heart.
Unfortunately, many of these APIs are getting the details slightly wrong and in doing so are producing invalid JSON. Browser vendors take note: you can still be the first modern browser to implement a proper offline mode! That in itself is HUGE. I'll be writing a lot more about this in the future. Ajax requests are instead made through an invisible Flash file that uses Flash to load the data, parse the XML, extract some CDATA and pass it back to _javascript_ to replace a div.
getSelection and associated methods. The slides were on automatic, so the presenters had to be able to time their talk precisely to match up with their slides. Remember, all valid JSON is valid _javascript_ but the opposite is not true; JSON is a subset.
Don't use libraries as crutches; if you're not prepared to figure out what the library is doing for you you'll end up in a world of pain further down the line. _javascript_ Libraries are an enormous topic but I felt we did them justice considering the time available.
The big four all have active communities, which means less bugs, more support and a faster rate of improvement.
In _javascript_, that means that libraries that mess with Object. If you plan to evaluate some existing libraries these make an excellent starting point. Browser vendors take note: you can still be the first modern browser to implement a proper offline mode! Both were excellent events in their own right, and great examples of event organisation done on a small to non-existent budget.
If you plan to evaluate some existing libraries these make an excellent starting point. They cover the bases effectively and each one offers something interesting that makes it worth studying in its own right.
Overall though it rates extremely well.
I'm still using it, although some of the things I liked initially have faded while others have emerged. I've met people who think that a Web Service is any application that you access over the Web - and it's easy to understand their confusion. prototype or pollute global namespaces should be treated with caution. I suppose it's looking for any link on the page with 'Next' as the link text. The following is all the browser-forking code you need to cover every available major browser.
