Microsoft Releases TypeScript 1.1 CTP, Offers Over 4X Performance Improvements

Typescript

Microsoft today announced the availability of TypeScript 1.1 CTP for Visual Studio “14” CTP4, Visual Studio 2013, npm, and as a source release. This TypeScript release includes the new compiler core redesigned to both perform better and lay the groundwork for future language features. In fact, it offers over 4x performance improvements. The 1.1 CTP compiler is compatible with projects built with the 1.0 compiler.

While this release updates the compiler, the editing experience in Visual Studio is still powered by the 1.0 compiler technology.  Our next goal is to bring this language service up to date with the rewritten compiler and finish modernizing the experience for command line compilation and IDE editing.  This will allow IntelliSense, code navigation, and other code editing tools such as Visual Studio a way to leverage the new compiler infrastructure. Until the language service has moved to the new compiler, you may see differences in error reporting. This work and the work to align with ECMAScript 6 is ongoing.  If you’d like to help with this work by contributing bug fixes, filing bugs, and dogfooding the latest code, please join us on our GitHub repository.
