Reviews for this release

A fantastic language and conceptually solid. However this release is marred by horrendous bugs. Large projects can cause VS to hang periodically, crash or (even worse) consume all system memory. Managing references and dependencies for large multi-file projects when performing single-file output is extremely difficult and requires a lot of care. Fix the bugs and it'll be a great tool.

i like - no! i love typescript! the integration into VS 2012 is still a little buggy (ghost errors, unpredictable compile-on-save) but its getting better and better. The compatibility to ECMA6 is also very nice! Good job so far!

0.9+ is already quite good and stable. Compiler works fine, but I haven't tested it for anything really huge, just small html5 games. I'm using JetBrains WebStorm 7 - it's all good, but sometimes file watchers require manual reset. Note: WebStorm 6 shows weird bugs with 0.9.1+, so consider upgrading as soon as possible.

Works well in my opinion. Some performance issues when using AMD, otherwise fine.

Love the language. Couldn't get "compile on save" to work. Couldn't get "compile on compile" to work. So i need to manually create a compile script, and manually add js-files to my solution and/or configure my build server. I'll stick to plain javascript for now.

Love typescript, hate compiler. Crashes vs2012 6+ times every day, some times i restart vs pre emptively when I notice it getting slow, otherwise I would be getting more frequent crashes. Intellisense can be very slow/crashy. I have no extra js/ts extensions that could be causing a conflict. Windows 7 x64. Hoping the next version has significantly better performance/stability.

Ghost errors in visual studio error list. Uses an cpu core to 100% after a few minutes. Intellisense is broken or very unstable

I'd like to give TypeScript 5 stars, but the integration with VS2013 is broken. Okay, they are both in beta but it's still broken. Web Essentials was filling the gap in VS2012 but now it's had TypeScript support killed, and the VS2013 support is nowhere near as good.

Love the idea of Typescript but the compiler is dreadful. Crashes Visual Studio 2012 and 2013 regularly. Gets VS into a state where it works for about 2 minutes then freezes and crashes. Intellisense is slow to non-existent. Lots of erroneous compile errors. It's so bad it's actually killed my productivity for at least a day.

I personally have never had an issue (ever) with using TypeScript, and it seems quite fast for normal projects, so for those having issues perhaps check your VS extensions for conflicts (disable them all if you have too to test). Anyhow, keep up the great work people! I know you're on the right track - but please, never take away from the fluid and dynamic nature of JavaScript (re. classes).

Recent complier changes have made this language unusable for large scale applications. Visual Studio 2012 now crashes once every 10-15 minutes of usage. Very disappointing.
by TimMc on Oct 7, 2013 at 1:35 PM
0.8 was great. 0.9 in VS 2012 caused me lots of frustration. 0.9.1 in VS 2013 RC is very smooth and the language is so great anyway. Moved from Coffeescript to Typescript and can say it is soo much better. And it is in line with future JS, so this is really a perfect shot.

So I am really close to giving this a 5 star rating. Using Typescript as a language has been awesome especially when re-factoring code. The tooling has been inconsistent between versions but I realize that this is still Beta.
by runxc1 on Oct 1, 2013 at 3:45 PM
The language is great, but the tools are so far only barely tolerable. Compiler error reporting improved on previous releases, but still flaky. Occasional bad JavaScript created, but so far have been able to work around it. Please keep up the improvements - it's going in the right direction.

I'm sorry guys, though I love Typescript and using it for almost a year, I'm getting more and more disapointed with it. Still too slow VS intellisense, too much CPU load, hours of code migration at every new breaking change... Im' really about to give up.
by props44 on Sep 23, 2013 at 2:50 PM
I'm really happy about this release and the pace things are going. is quite stable and works very well. For external modules (amd/commonjs), it still needs some improvements, but for anything else it works very well.

Loving the progress on this project, and looking forward to the 1.0 release.
by Barguast on Sep 11, 2013 at 11:58 AM
Where is the no star option. Getting existing libraries into a project the most painful experience I have had working on a project. Working with a designer and trying to explain to them they cant just add a javascript library so now I have to do all the designers work too. Now you have to be a .net developer to do any javascript work.
by JCPhlux on Sep 5, 2013 at 2:31 AM
Changed my rating, because after more testing the compiler, i had found that in some cases it produces incorrect javascript. That means, the compiler is unreliable, and can produce hidden bugs in output javascript, even the source is correct. For example look at workitem 1614 to see the compiler produces wrong javascript

Still suffering from horrible performance, both on the command line and in Visual Studio 2012. IDE memory consumption climbs from < 1GB to nearly 3GB as soon as I start editing a type script file. Painfully slow response from intellisense, etc. On the command line, running tsc.exe even against a two line HelloWorld.ts file takes way longer than it should. The Playground page compiles faster!

Moving from 0.8.3 to had been quite painful due to breaking changes and introduction of generics. However, we now get a much more types in our code, and therefore our code base is way more stable. had a performance issue in VS 2012, but the new one is just perfect. Keep up the good work!
by JeWaVe on Sep 1, 2013 at 1:39 PM
By removing a certain file from my solution I was able to get it to compile, but even still the performance has been pretty bad for me. It takes 15-30 seconds for the intellisense and redlining to catch up to what I just typed.
by MgSam on Aug 29, 2013 at 2:44 PM
Changed rating, previously noted that "compiled" js file isn't Published - apparently, only on the demo file. Adding a new ts file acts normally. Still, it's an issue.

Thanks guys
by basarat on Aug 28, 2013 at 10:09 AM
getting better, the version seems to be more stable but the error list r still useless. not sure if worth moving from
by Natikr on Aug 25, 2013 at 1:38 PM
Much better than, but: 1. "Error List" is no longer usable - most errors don't disappear from the list until related files are reopened. 2. lib.d.ts still contains invalid definition of MutationObserver's constructor. It should require one argument - callback.
by Qxx123 on Aug 23, 2013 at 7:26 PM
Great. With only minor changes, my 0.8.3 project compiled without issue. Much more stable than previous releases.
by web2nr on Aug 23, 2013 at 2:32 PM
Finally, I can compile my project without a lot of errors and memory leaks. Thanks.
by rsuter on Aug 23, 2013 at 2:25 PM
My previous problems with strange compiler errors are gone, and all the definitions got picked up nicely.
by prgjonas on Aug 22, 2013 at 6:24 AM
Much better guys, at least in my scenarios. It seems fast, it seems stable, and it doesn't take down VS every 30 seconds - always a plus, that last one.
