Dart 1.0 Released 121

stoolpigeon writes "Yesterday marked the release of Dart SDK 1.0, a cross-browser, open source toolkit for structured web applications. The Dart SDK 1.0 includes everything you need to write structured web applications: a simple yet powerful programming language, robust tools, and comprehensive core libraries. The language has been somewhat controversial, but Google continues to move it forward." Reader slack_justyb adds some more detail: "The new release brings a much tighter dart2js compiler reducing overall JavaScript output up to 40%; Dartium — a version of Google Chrome that has the DartVM in addition to the JavaScript VM as native to the browser; PUB, a package manager for Dart add-ons; and several favorite 3rd party plug-ins that now come out-of-box, in addition to a lot of work for Dart server-side tools that can work to automate server side tasks and help in the construction of web pages. However Dart has many critics not only from the IE and Apple camps, as one would guess, but from the Firefox and Opera camps as well. In addition to the low adoption of Dart from third parties there are some asking where does Dart go from here? Especially considering that Google is one of the strongest pushers for EcmaScript 6."

    If you've used JS in the past you'll see immediately why DART is so welcome. It's actually SANE!

    My productivity is probably 200% greater in DART then JS. But don't take my word for it, I'm jsut an ana coward!

    It seems rather imbicilic to say that Dart2JS is faster than JS.

    • It's rather imbecillic to handwave it without providing any reasoning behind it. Look what Mozilla is doing with asm.js and "compile to javascript" compilers.. You can compile a high level language to a low level, restricted subset of javascript which then runs very fast in the browsers's JIT engines. Doesn't sound too great maybe but the resulting execution speed can possibly be better than by using javascript's high level features and libraries instead.

        Ah, sure, the source is available, but what about the source of the compiler what was used to compile it? If you can't get the source of the original compiler, the only recourse is to actually check the output of the compiler - I suppose you could also *de*compile the compiler and check *that* source too.

      • If you haven't tried it, you should try Firebug. It helps debugging Javascript in the browser quite a bit.
      • Chrome has the best debugger I have seen. I find easier to debug Javascript code than Java code on Eclipse. It is one of the reasons I don`t like TypeScript and its similars, they compile down to Javascript which makes harder to debug the original code because the debugger only sees the Javascript code.

          I never found Typescript's output to be that hard to read, since it preserves comments and changes the code very little apart from rewriting class definitions.

          You can enable source maps, which the Firefox/Chrome debuggers can use to show you the original code when debugging compiled code. And some minifiers like UglifyJS can transform source maps to continue working after minifying.

      I don't hate JavaScript, but I wish it started to have a real and modern API.

I am not talking DOM manipulation level APIs like jQuery, but about a good collections, async, crypto, etc APIs.

      I think your arguments are pretty valid and I am by no stretch of the imagination a pro-Dart guy, but I believe that the "cross browser" claim comes from the olden days of cross platform languages. C/C++ had (has, just in case the past tense is a really bad choice) cross platform compilers they take C/C++ code and compile it to a language that the target platform understands. For example, C to ARM/x86/amd64/MIPS... compilers.

      So my guess here, and it is just a guess, is that Google is using the same rationale to justify calling this a "cross browser" language, because the compiler can turn Dart into a language that can be understood by other browsers, much like a C compiler can compile into different paltforms. Arguments about if that is an accurate equation are totally justified and most likely will ensue hereafter. I'm just tossing up a guess as to why Google felt like that was an accurate statement.

I think the better question would be how much political effort would it take to get a plug-in for FF and/or IE into the hands of people? Pure JavaScript folk are pretty damn hard-core about their language and Dart to them just seems like a solution to a non-existent problem. Besides, with Dart being a plug-in, you'd have websites once again going into the "check for plug-ins" h

        What? Do you mean 2.6.0 RC1? 2.6 looks to be more of a clean up of the 2.5.1 stuff rather than anything new. If anything the main thing that 2.6 brings is that they brought Java 7 into the picture. I wouldn't say that Google *has* abandon GWT, but they sure are making the common gestures of getting ready for a good old fashion keelhauling. []

        Now for just my opinion, GWT sucks. It's a messy looking API and lacks a ton of flexibility. For example, trying to implement custom UI for your web page is painful and totally unpleasant. More so than say making the same customer UI in Java Swing (which is pretty painful in of itself). In my opinion, and you my mod me down for it, is that anything that is worst to do in (insert framework here) than it is in Java should not exist.

        • If you find Swing painful your comment about GWT loses quite a bit of credibility.
          And your last sentence coins it, lol. You find Swing the most difficult "framework"? (Hint, it is no framework, it is a library) Sorry that is a total laugh ...

          • Well I work with Java all the time and I find Swing great to use, but when I want to build my own user interface elements, then yes, I find it very painful indeed. I've done custom widgets in Cario/GTK, .NET, and even for Android; and Swing is pretty up there for the bar that needs to be crossed to have a custom widget. I don't find Swing all that difficult to use at face value but just mucking about AWT or even SWT is far better than trying to muck around and build custom GUIs in Swing.

              OTOH most of the time it is more efficient to write your own look and feel instead.

    • GWT has been open sourced. I am hopeful that this can only be a good thing. There is still at least as much activity on the project as when it was not open source.
