Utah JavaScript gurus... thoughts on TypeScript?

Thanks,

Aaron

Well, TypeScript is basically ES6 with types.

Typing really helps when building tools/IDEs (even if it's only compile-time checking), but code inspections, refactorings, etc will definitely benefit (I imagine that's why Microsoft/Visual Studio are pushing for this).

Whether typing helps with large apps, teams, readability, etc are all a matter of personal experience and opinion, but I would argue in favor of it.

I actually really like it. The current problem I have with coffeescript is that it feels hard for us to move our existing code to a totally different language. I don't think I can convince my entire team to move to coffeescript. And even if we did, it would make a larger barrier of entry for someone new in the codebase. 

TypeScript is interesting because as John mentioned, it is essentially ES6 with a few extra features. It is a superset of javascript, so your existing codebase is "TypeScript".  This makes it easier to move an existing project towards. The syntax isn't that foreign and it is what the industry will be moving towards with ES6. 

Overall I think it is great, other than that most tooling seems to be built around Visual Studio and I am not going to do web dev in Visual Studio....ick. I'll have to get my feet wet before I get any stronger feelings :)

I agree mostly with Miguel de Icaza's first impressions:
http://tirania.org/blog/archive/2012/Oct-01.html, most especially that
the benefit is really only useful inside an IDE and right now that
means only Visual Studio....not sure how many of you develop on
Windows (and with Visual Studio) but I sure don't. That's not to say
that Visual Studio isn't great, it is awesome, just that I don't have
resources to buy it and cringe when trying to develop on Windows.

They've certainly pitched it the right way -- it's a superset of JavaScript, a free open-source transpiler exists, it can be transpiled to ES3 on the fly in browsers that don't natively understand it, etc. Seems basically similar to the CoffeeScript approach, and that one's certainly gained a loyal following.

 

Like John said, anything that helps organizations better manage large code bases seems like a win.

JavaScript; it's the new Assembly.

Dart, TypeScript, ES6, CoffeeScript and more, all compiled down to a single language to be compiled down to machine code.

It's monster language madness madness madness on monster language Sunday Sunday Sunday. Be sure to tune in for the most exciting event of the year. Tickets must be purchased in advance. Inconvenient convenience fee may apply.

We're bringing TypeScript support to WebStorm/Intellij (which should help Mac/Linux guys): http://youtrack.jetbrains.com/issue/WI-13714

It's interesting that since we already support ES6 it's now just a matter of bringing our type support from ActionScript over to ES6 (that's an over-simplification, but it holds pretty true).

We'll have all the inspections, refactorings, etc of all the other static languages, so it should be pretty interesting once its all put together.

I am a little scared that we'll start seeing AbstractFactorySingletonBuilderBean classes in JS though...

Dart though can be standalone and run in the Dart VM. I kind of wish
that the Dart and TypeScript guys could get together and merge some
ideas. I like TypeScript's syntax more than Dart's but I like that
Dart can exploit the use of the types to run more efficiently if run
in the VM.

Don't want any of this in your js codebase? http://javadoc.bugaco.com/com/sun/java/swing/plaf/nimbus/InternalFrameInternalFrameTitlePaneInternalFrameTitlePaneMaximizeButtonPainter.html

I can't remember if somebody posted it already, but I found out today that it supports source maps , which is awesome!

I still need to make it to my first one, but tonight is not going to work for me either. Maybe next time.

Thanks
