New Asynchronous APIs for Dart. The latest Dart SDK now provides a cohesive API for asynchronous programming.
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. Dart Tips: Short Video Tutorials about Dart. Sometimes, you only have 5 minutes.

Ep. 2: Runtime Modes. 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.”
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 in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. 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.
The language was announced in November 2009 and is now used in some of Google's production systems. 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. A second compiler, gccgo, is a GCC frontend. Ken Thompson states that initially, Go was purely an experimental project. Referring to himself along with the other original authors of Go, he states: When the three of us [Thompson, Rob Pike, and Robert Griesemer] got started, it was pure research.
