Dart 1.5 makes it easier to develop for the mobile web. It’s important for web experiences to work great on mobile devices.

Dart 1.5 makes it easier to develop for the mobile web

The latest release of the Dart includes a development version of Dartium – Chrome with the Dart Runtime – which runs on Android devices. We’ve also updated the Dart Editor to support debugging mobile web apps written in Dart. You can set breakpoints and debug exceptions with Dart web apps running on a device with the same development flow that exists on your development machine. Check out the documentation to get started. The Dart 1.5 release cycle was short – just four weeks – but we are excited to continue delivering great improvements to our platform and tools. We have also released an update to the Dart Polymer package and shipped two sets of new Polymer elements. core_elements gives Dart developers access to all Polymers infrastructure components. paper_elements contains Polymer elements that follow the material design pattern that was announced at Google I/O 2014. Dart : l'alternative à JavaScript de Google bientôt standardisée. New Asynchronous APIs for Dart.

The latest Dart SDK now provides a cohesive API for asynchronous programming.

New Asynchronous APIs for Dart

Some of the new or improved classes in this release include Stream, a sequence of asynchronous events, and Future, a single asynchronous result. The Stream class is new and delivers on a common developer request for a more unified approach to events. An event can be any Dart object, which makes Streams very flexible. Consumers of a Stream can listen for events, and streams can be piped, transformed, filtered, and more. We are working to apply them across HTML, I/O, isolates, and more. Query('#button').onClick.listen((e) => submitForm()); Here is an example of streaming the contents of a file. The Future class, which represents a single value available in the future, was cleaned up and is much easier to use. Some of these changes are not backwards compatible. Over the following months we will continue to work on the libraries, applying the new asynchronous models. Dart Tips: Short Video Tutorials about Dart.

Ep. 9: Exceptions Ep. 10: Classes: Setters & Getters. 40' video sur Dart, Google “evil plot to make it easier for you to build web apps.” Google, the company whose code of conduct begins with the words “Don’t be evil,” has uploaded a new video to its developer channel talking about its programming language Dart, which Google calls its “evil plot to make it easier for you to build web apps.”

It’s a 40-minute video that talks about the programming language and its features. “When we announced Dart, it kicked up a bit of a dust storm,” says Dart engineer Bob Nystrom in the YouTube description for the video. “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,” he adds.

Google has been uploading tons of videos of sessions from Google I/O, and these two deal specifically with the Dart programming language, so if you’re looking to learn more about it, and were unable to attend the event, you’re in luck. The first video is from the session: Dart – A Modern Web Language. Here’s the video’s description: The two creators of Dart will discuss the rationale behind Dart’s design and its impact on web scalability and performance. They’ll also present how Dart helps developers innovate by increasing their productivity without breaking backwards compatibility. The second is from the session: Migrating Code from GWT to Dart. Curious to learn how to port your GWT code to Dart?

Google Dash/Dart, Go, a Cloud IDE „Brightly“ and the future of Javascript

Mail from Google buzz through the Internet and it includes some interesting Details about the future of Javascript. Also it includes an announcement for the presentation of the new language Dart on GOTO which is going to start at the 10th of October. The Problems of Javascript In the opinion of Google (and some others) Javascript offers many problems. For example there are some Performance problems but also there are some problems with the new tooling for big projects.

Improve Javascript or try a new beginning? For Google there are two possible Options: Improve the already existing Javascript implementation slowly which would probably take a lot of time or create a new type of language for the Web: Dart (in the Mail it is still called Dash) Googles efforts in the Javascript environment In the Mail it was accented, that Google is still going to support ECMAScripts (especially the next step Harmony).

Gilad Bracha: Dart - A Well Structured Web Programming Language

Dart is a purely object-oriented, class-based single inheritance optionally typed language with actor based concurrency. The design of Dart is subject to two challenging constraints: efficient compilation to JavaScript and instant familiarity to mainstream programmers. Dart may be deployed on both client and server, either via compilation to JavaScript or on its own VM. Dart (langage informatique) A language for structured web programming. By Lars Bak, Software Engineer, Dart Team Cross-posted on the Chromium Blog Today we are introducing an early preview of Dart, a class-based optionally typed programming language for building web applications.

a language for structured web programming

Dart’s design goals are: Create a structured yet flexible language for web programming.Make Dart feel familiar and natural to programmers and thus easy to learn.Ensure that Dart delivers high performance on all modern web browsers and environments ranging from small handheld devices to server-side execution.Dart targets a wide range of development scenarios: from a one-person project without much structure to a large-scale project needing formal types in the code to state programmer intent.

To support this wide range of projects, Dart has optional types; this means you can start coding without types and add them later as needed. We look forward to rapidly evolving Dart into a solid platform for structured web programming. Dart Synonym: Translations from JavaScript. Dart: A language for structured web programming.

Dart Language Specification (0.10)

Dart: Structured web apps. Dart Language Specification (0.07) Www.dartlang.org/docs/spec/latest/dart-language-specification.pdf. Go (programming language) Go, also called golang, is a programming language initially developed at Google[6] in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson.[2] It is a statically-typed language with syntax loosely derived from that of C, adding automatic memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library.

Go (programming language)

The language was announced in November 2009 and is now used in some of Google's production systems.[7] Go's "gc" compiler targets the Linux, Mac OS X, FreeBSD, OpenBSD, Plan 9, and Microsoft Windows operating systems and the i386, amd64, and ARM processor architectures.[8] A second compiler, gccgo, is a GCC frontend.[9][10] Ken Thompson states that initially, Go was purely an experimental project. Referring to himself along with the other original authors of Go, he states:[11] When the three of us [Thompson, Rob Pike, and Robert Griesemer] got started, it was pure research. Go (langage) The Go Runtime Environment - Google App Engine. Welcome to Google App Engine for Go.

With App Engine, you can build web applications using the Go Programming Language. Your Go application runs on Google's scalable infrastructure and uses large-scale persistent storage and services. Introduction App Engine builds and executes Go application code using a safe "sandboxed" environment. Your app receives web requests, performs work, and sends responses by interacting with this environment. The Go SDK provides an interface similar to the standard Go http package; writing Go App Engine apps is akin to writing stand-alone Go web servers. The Go runtime environment uses Go version 1.2. The SDK includes an automated build service to compile your app, so you'll never need to invoke the compiler yourself.

The Go runtime environment for App Engine provides full support for goroutines, but not for parallel execution: goroutines are scheduled onto a single operating system thread.
