This looks great, but the IDE seems to be one of the key features, so we're going to need something other than Visual Studio.

EDIT: they've got syntax highlighting for some other editors, but full completion and error reporting is still needed http://blogs.msdn.com/b/interoperability/archive/2012/10/01/...

Weird that I didn't spot a friendly list of features.. seems to have some cool ones, like a shortened function expression (from the doc PDF): (x) => { return Math.sin(x); } and modules, which are implemented using the immediately invoked function expression pattern: module M { var s = "hello"; export function f() { return s; } } Syntax seems more clear than CoffeeScript and tool chain will probably shape up better. L…

I like the shortened function form. I played around with CS for a while before going back to JS, but I do miss being able to do something like:

    var names = people.map((p) -> return p.name);
(or something along those lines). Funnily enough, it reminds me of C#'s LINQ:

    var names = people.Select(p => p.name);

Apparently ECMAScript 6 is considering some other forms of function literals as well: http://www.2ality.com/2012/04/arrow-functions.html

Back in the day, Microsoft would use a strategy called "embrace, extend, extinguish." http://en.wikipedia.org/wiki/Embrace,_extend_and_extinguish Recently, Microsoft has been pushing Javascript very hard (embrace) and now it looks like they've started the "extend" phase. Luckily, no one really worries about them being able to pull off the "extinguish" part anymore... they just don't have enough market power these day…

Except that this is fully open source, which makes it a little difficult for MS to retain control over it, no?

Re-reading late 90s M$ memes gets old after a time.

Codeplex/samples/simple ( http://bit.ly/Svcc4Y ) is the same as the CoffeeScript constructors doc section ( http://bitly.com/PnLtGy )... Wonder what other stuff they borrowed from CoffeeScript?

Maybe that's a good idea because it makes it easy to compare the two?
