"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," writes Dart developer Lars Bak.
"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," he adds - but there's a problem.
"We believe Dart will be great for writing large web applications," Bak writes. "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."
Full details of Dart, plus downloads for the compiler and virtual machine, are available on the Dart website.
