Dart: A language for structured web programming
lunes, 10 de octubre de 2011
Cross-posted on the
Google Code Blog
Today we are introducing an early preview of
Dart
, a class-based optionally typed programming language for building web applications. 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 believe Dart will be great for writing large web applications.
Dart code can be executed in two different ways: either on a native
virtual machine
or on top of a JavaScript engine by using a
compiler
that translates Dart code to JavaScript. This means you can write a web application in Dart and have it compiled and run on any modern browser. The Dart VM is not currently integrated in Chrome but we plan to explore this option.
The language comes with a set of basic libraries and tools for checking, compiling, and running Dart code, all of which will evolve further with your participation. We've made the language and preliminary tools available as open source on
dartlang.org
. Check out the site to give feedback, learn more about Dart, and participate in its development.
We look forward to rapidly evolving Dart into a solid platform for structured web programming.
