Watch Dart's plan to make it easier for you to build web apps

Posted by Seth Ladd

Bob Nystrom, engineer with the Dart project, recorded a screencast of his presentation titled "Dart's plan to make it easier for you to build web apps".



From the video's abstract:
When we announced Dart, it kicked up a bit of a dust storm. In this talk, I discuss the challenges that Google and others face when building web apps today. I introduce Dart and show how its features were designed specifically to address some of those challenges.
You'll see how Dart protects you from many of the dark corners and sharp edges of JavaScript and the DOM. When your programs grow and evolve over time, you'll see how Dart can help keep your app nimble and maintainable. Thanks to Dart's Dart to JavaScript compiler, you'll see how you get all of that while still being able to run on any browser that supports modern JS and without the bad karma of fracturing the web.

ElementList now deprecated, use List<Element>

Posted by Seth Ladd

Earlier today, Vijay Menon (engineer on the Dart project) posted the following news:

As a simplification, we plan to remove NodeList and ElementList as public types in dart:html shortly.  We ask instead that you use List<Node> and List<Element> respectively (or just plain List).  You should be able to move to these types today.
This is good news for a further simplified and Dart-friendly HTML library interface.
