From whatever little I see, I am already hating it :-) This looks like Java for Javascript, if that makes any kind of sense. We are in the year 2011, PL design has progressed so much since 1990 that such an anachronism is unpardonable. I sincerely wish that companies like Google focus on hiring the right kind of person for designing programming languages. What is frustrating is that there are so many people who can d…

Agree with parent comment. My opinion, so far: Overall: uninspired. Below what I was expecting. Probably good for Google goals (tooling, migrating developers, etc) The language is somewhat interesting, but unfortunately saddened by an incredibly boring syntax. At this point, I am thinking that they would have been better off just going with the Go language for this. Looks like something good to migrate fleets of java…

Also, string interpolation using only double quotes has bothered me in Rails. That was the one feature I saw that they supported, although now that I think about it, Rails probably adopted it as a convention to prevent excessive escaping.

The one thing I don't understand is why people work on new languages for the browser instead of giving us a platform (virtual machine / intermediate representation, whatever) to implement languages against. I mean here in this thread we are already seeing it. Some people like semicolons, some people don't. Some people like a prototype based object system, some people like a class based system. And on and on. I think…

This is what JavaScript is trying to be, with the latest revision. They're explicitly trying to make it a better target language for things like ClojureScript and CoffeeScript.

Well yes, but I think the motivation here is more 'since javascript is the only game in town, we'll have to compile to that'. I am not aware of any changes made to Javascript to make it easier to compile to it. And I don't think anyone would choose Javascript as their runtime environment if they had a choice.

I like Clojure and have dabbled with clojurescript but the workflow feels pretty hacky and it is clear that this is not what javascript was made for.

This is not a product launch.

The lack of browser support implies architectural choices that will always make old browsers lag behind. It means that the generated JS uses modern JS features. If it would be easy to support older browsers, they would've done so already - at least to some extent. The fact that it compiles only to JS for the very latest versions of a small number of browsers gives me the impression that a lot of language/compilation…

Google officially started phasing out support for IE6 in January 2010. It's reasonable to assume that new languages (etc.) released by Google would be aligned with their general policy on which browsers are to be supported and which are not.

Aaaarghhh! It is full of semicolons. Is it really necessary in the 21st century to create a language that terminates lines with semicolons? I am sure I have seen some other languages in the past that get by just fine without them.

This is completely the wrong thing to do. Google should be proposing a standard, open, byte-code compatible, Intermediate Language standard that can run Javascript and in the interim run on Javascript. That is something I could see Mozilla and Apple getting behind. Only once they have actively campaigned for this should they be adding new languages to the browser which fracture the web. I had hoped that Dart would su…

+1000. Give us a platform that people can grow languages on! Maybe the DartVM could become something like what you describe in the same sense as the JVM/CLR is a platform for many languages now? But since their pushing the language it doesn't seem to be the stated goal... sad ;(

My hopes were high, but the more read about it, the more it started to look like Java:

    class Foo implements Comparable Observable Deniable ...
Why not have interfaces like in Go, where you just define a set of methods and all classes having the methods will automatically implement the interface.

    Collection
    HashMap
    HashSet
    LinkedHashMap
    List
    Map
    Set
Why not just Array and Hash? And what's up with the whole generics thing - that's just plain old Java.

    int
    bool
    String
    Object
Why do some types start with lowercase and some with uppercase letter. Why not use a sensible naming convention?

    square(n) => n + n;
    square(5); // returns 25
    square2(n) { n + n; }
    square2(5); // returns null
Why not have an implicit return value everywhere?

I could go just on and on...

The language isn't done yet. Now is the time to let us know if you want semicolons to go away. I know some of us on the team do too, but public interest will help a lot.

Yes please. No semicolons. And please make it look a lot more like CoffeeScript than Java.

Am I in the minority? I madly in love with braces and semicolons. And, madly hate Pascal, Python & Ruby for the absence of them.

> Please try and hire people like Oleg Kiselyov, Simon Marlow, Erik Meijer All brilliant people, but you have to remember that not everyone thinks types are all that matters. I like type systems, but the majority of the world's shipped code was written in languages with unsound type systems.

Then what about "hire people like the creators of PLT Scheme / Racket" - they have extraordinary strong scientific background too.
