Dart: A Structured Web Programming Language



Gilad Bracha introduces Dart, Google’s new language for the web, explaining the reasons behind its conception, what it is and what it is not, some of the main features, and unveiling plans for the future.


Gilad Bracha is the creator of the Newspeak programming language and a software engineer at Google. Previously, he was a VP at SAP Labs, a Distinguished Engineer at Cadence, and a Computational Theologist and Distinguished Engineer at Sun. He is co-author of the Java Language Specification, and a researcher in the area of object-oriented programming languages.

  • Compare with GWT?

    How does Dart compare with GWT? One difference is GWT is Java compiled to JavaScript, Dart is a new language compiled to JavaScript. Under what circumstances would I prefer one over another?

    The real motivation behind Dart is to make it run natively in the browser (not via javascript).

    Today it’s hard to deliver a large amount of code to the browser using javascript source files.

    Ironically, Dart's mission is very close to Java's original mission.

    Java/GWT don't really embrace HTML/DOM other than to use that as a delivery vehicle for applications. I suspect Dart will be a better HTML citizen just like javascript is today.

    Also, Java is showing its age. Dart is a multi-paradigm language supporting OO, functional and Actor paradigms (like many other contemporary languages).

    If Dart never takes off other than just as a source language for javascript then it would be a waste. Better still Google should focus on the VM under Dart and make that directly addressable so that any language can be ported to run on the web - not just Dart or javascript.

    GWT is more of a framework. Dart has a larger scope than that of a usual framework even if some of Dart may also work as a framework.

    With a DartVM, running Dart in a browser for development purposes if not for deployment purposes will also help to speed up the usual process of edit a file, reload the page to see the changes. GWT presently seems to take over several seconds to test the changes.

    There's a potential to use the DartVM to power application deployments in the Android devices. So you don't need to compile it all to JavaScript to run, necessarily.

    As both GWT and Dart make for good frameworks, you may use either one if you so wish.

    Dart is sort of the future. GWT is the established and successful present. Eventually, the toolkits available to GWT will also be available to Dart so the differences will be blurred even more.


  • Echos of Visual Basic

    by Polly Shaw,

    I feel uneasy with the decision to appeal to intuitive understanding rather than logical correctness regarding the covariance of generic types because I'm afraid it may result in more confusion rather than less. I remember that VB<=6 had arrays that were 1-based by default for the same reason, but as this behaviour could be overridden and some developers preferred 0-based arrays it led to confusion over whether any particular array was 1-based or 0-based.
