Next VS2013 update to make TypeScript a first-class citizen
Microsoft's TypeScript web development language is almost ready for prime time, and by the time the next update for Visual Studio 2013 arrives, TypeScript 1.0 will be treated as a first-class language by Microsoft's IDE.
So sayeth S. "Soma" Somasegar, corporate VP of Microsoft's developer division, who announced a new community technology preview (CTP) release of the forthcoming VS2013 Update 2 on Tuesday.
"TypeScript is today being used to build products all over Microsoft, including Visual Studio Online, XBox Music and Video, parts of Bing, and the IE11 Developer Tools," Somasegar said. "Outside of Microsoft, TypeScript is being used in projects like Adobe's Digital Publishing Suite."
Enter Visual Studio 2013 Update 2. The final version of the update is still a few months away, but Tuesday's CTP release shows off how the next version of VS2013 will treat TypeScript as a first-class language, complete with IntelliSense, code navigation, code refactoring, and other features that developers have come to expect from Microsoft's tools.
The release coincides with Microsoft's announcement that the TypeScript language has reached the first release candidate of version 1.0. That means it is now feature-complete for its initial release, its syntax is considered production-ready, and the TypeScript compiler outputs code in a way that fully complies with the 1.0 specification.
The language itself has changed slightly since the last release. In TypeScript 1.0 it's now easier to use the "any" keyword as a wildcard when declaring types, and handling of generic types has been simplified. Interface overloading has also been made more straightforward, making it easier to extend the standard lib.d.ts library. In addition, Microsoft has also added support for touch events and WebGL to lib.d.ts.
Visual Studio 2013 Update 2 CTP 2 is available for download beginning on Tuesday – though as with all CTP releases, Microsoft cautions that it's currently suitable for experimental use only.
TypeScript 1.0RC1 – also known internally as TypeScript 0.9.7 – is available from the TypeScript homepage, and its source code is downloadable from Microsoft's CodePlex site under the Apache 2.0 open source license. ®
