TypeScript 0.9 Preview Released

S. Somasegar announced TypeScript 0.9 release availability that is available during the Build event. TypeScript is a scripting programming language from Microsoft.

TypeScript is a language for application-scale JavaScript. TypeScript adds optional types, classes, and modules to JavaScript. TypeScript supports tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. 

In his blog post, Somasegar wrote:

Today, I am happy to announce a major milestone in the evolution of TypeScript, with the 0.9 release. Along with important new language features and improved tooling capabilities in Visual Studio, we’ve done considerable work to scale the TypeScript language service for large application development, giving developers a smooth, interactive experience regardless of project size.

TypeScript has already been positively impacting web development, even as an early technical preview.  Inside Microsoft, teams in Bing, Team Foundation Server, So.cl, CodePlex, and elsewhere are using TypeScript in production applications, some in excess of 200k lines, leveraging TypeScript’s ability to scale quickly with the assurances provided by a type system and rich IDE support.  In the broader JavaScript community, projects like Turbulenz and Starling.js have leveraged TypeScript as part of new development libraries and kits.  We’re also seeing teams building enterprise and consumer applications for the web, Windows Store, and server -- all with TypeScript.
