WEB PROGRAMMING LANGUAGE DART BY Google | Dart 1.0: A stable SDK for structured web apps

Dart SDK 1.0, a cross-browser, open source toolkit for structured web applications. In the two years since first announced Dart, This release marks Dart’s transition to a production-ready option for web developers.

The Dart SDK 1.0 includes everything you need to write structured web applications: a simple yet powerful programming language, robust tools, and comprehensive core libraries. Together, these pieces can help make your development workflow simpler, faster, and more scalable as your projects grow from a few scripts to full-fledged web applications.

On the tools side, the SDK includes Dart Editor, a lightweight but powerful Dart development environment. We wanted to give developers the tools to manage a growing code base, so we added code completion, refactoring, jump to definition, a debugger, hints and warnings, and lots more. Dart also offers an instant edit/refresh cycle with Dartium, a custom version of Chromium with the native Dart VM. Outside the browser, the Dart VM can also be used for asynchronous server side computation.

For deployment, dart2js is a translator that allows your Dart code to run in modern browsers. The performance of generated JavaScript has improved dramatically since our initial release and is in many cases getting close to that of idiomatic JavaScript. In fact, the dart2js output of the DeltaBlue benchmarknow runs even faster than idiomatic JavaScript. Similarly, dart2js output code size has been reduced substantially. The generated JavaScript for the game Pop, Pop, Win! is now 40% smaller than it was a year ago. Performance of the VM continues to improve as well; it’s now between 42% to 130% faster than idiomatic JavaScript running in V8, depending on the benchmark.

The Dart SDK also features the Pub package manager, with more than 500 packages from the community. Fan favorites include AngularDart and polymer.dart, which provide higher-level frameworks for building web apps. Dart developers can continue using their favorite JavaScript libraries with Dart-JavaScript interop.

Going forward, the Dart team will focus on improving Dartium, increasing Dart performance, and ensuring the platform remains rock solid. In particular, changes to core technologies will be backward-compatible for the foreseeable future.

Google intended for the language to be a replacement of the ubiquitous JavaScript support found in all modern browsers, but without any native browser support, code written in Dart had to be translated to JavaScript in order to work.

The language soon found itself written off as a laughing stock for producing large amounts of JavaScript when translated.

Two years on, the Dart team has created a better translator, dart2js, which is written in Dart and claims performance quicker than “idiomatic JavaScript”.

“dart2js output code size has been reduced substantially. The generated JavaScript for the game Pop, Pop, Win! is now 40 percent smaller than it was a year ago. Performance of the VM continues to improve as well; it’s now between 42 percent to 130 percent faster than idiomatic JavaScript running in V8, depending on the benchmark,” wrote Lars Bak.

Accompanying the SDK is Dart Editor, a development environment based on Eclipse that supports code completion, refactoring, jump to definition, a debugger, hints and warnings.

Please wait, You will get a pdf version of this new programming tool from my web.

Be happy and cheers.!!!
