The best way to think about it is that the schema is a DSL which can be used to automate code functions like validation, serialization, GUI display, reports etc.. That DSL needs to be able to cope with minor and major changes, and expressive enough to deal with complex conditional optional structures.

This approach shouldn't be applied everywhere (if the size of the dataset is trivial).  And, if the DSL isn't rich enough or the approach has failed before the solution is to fix the DSL rather than just resort to a non-machine readable schema document.  If you go typeless you've removed the ability to automate a large part of your system.

If there's no machine readable schema then each developer has to write their own serializer and deserialize code.  A process reading a complex message of 400 or more fields in a structured document would have verify the presence of each field before they use it.  This can lead to monotamaus, buggy code.

It's far easier to automate the task of verifying the message against one of the valid schemas.  Providing for basic for rules for non-break minor changes is a must.  The validation code can be generated - and once you have a valid message you can deserialize it so that you can programmatically access the contents.

Resorting to manual message validation and serialization as a way of solving the issue of tight coupling is really solving the sympton rather than the cause.  The real issue is to have a versioning strategy with a flexible automated code generation system that is designed for loosely coupled providers and consumers.

A good practical example of this is Google Protocol Buffers extension mechanism.  With ProtoBufs you can partially deserialize from a code generated class and load an extension schema in dynamically at runtime to access additional data.  Much like C#'s hybrid static and dynamic typing.

Dynamic typing is really just runtime validation.  If you want to validate code before runtime you should be able to.  Anybody that has written a large scale JavaScript application will know about the problems that TypeScript is trying to solve.

I'm a heavy CoffeeScript user and would definitely use this.  Couple of suggestions:

  • Line number correlation is important for debugging.  I don't remember what happened to the standard proposal - but some browsers would going to support this is JS.
  • Is there an option to minify?  Now that more information is known I would expect a minifyier could do a better job.
  • What about aync support?  Would like to see something like Iced CoffeeScript.
  • Is there an option to generate interface only .ts files for distributable libraries (essentially just the metadata)?

Also, would love to see a hosted dev environment for this Wink

Other than that - the new features look great.

Firstly, where are the delays and what are the activities?  If this is a carrier test delay, what are they testing?  Their native apps on the phone?  Why don't iPhone updates suffer the same delays (they are largely globally synchronized, looks like the carriers don't get a veto).  Why are phone devices different to 3G enabled netbooks for example?

My suggestions....

The answer is to emulate the iPhone model more than the Android model.  Locking down the platform is the first step, but locking down for the users and not the handset OEMs and carriers misses the point - we still see the same delays with testing.  

The best thing for the users is for Microsoft to use less OEM partners - we really shouldn't be cheering each time a new hardware partner is announced.  The carriers and OEMs are not interested in updates, they want to sell more units.  Will devices more than 18 months old ever get any attention from them, they would be spending money on encouraging their users not to buy new equipment or contracts. 

The real answer is to move as much testing in-house at Microsoft as possible.  Change the SLA with the carriers - move support to Microsoft.   Lock down the API surface area.

Also, use the community.  Roll out the update as an optional to all developer enabled handsets and let the community beta test it.  With all this time to market should be something closer to Apple's rather than Google's.

Are there really any optimizations that are truly JavaScript specific, and couldn't be used in other scripting languages?
