Kathy Walrath and Seth Ladd, members of Google’s developer relations team, show in this essay why Google Dart is a language to be considered (in a near future) for all your Web applications: First of all, they answer why a new language is required, the most important question in this matter, what JavaScript is good for… and what it lacks. After that brief introduction, they move on to the real language (what it looks like, how you can use it, what libraries are already available – for example, Box2D, the physics engine behind the well-known mobile game Angry Bird -, where you can use it – and the idiosyncrasies of the server VM).

It’s not intended as a language tutorial (after all, it is still being debated), this is often repeated; however, you’ll find some pieces of code: this is real thing, not just a dream. It would be hard to explain isolates without showing some code. I would say the main goal is to demonstrate Dart is not just some funny thing that won’t survive any longer, that it deserves some interest from Web developers. And it does it well!
