Microsoft announced the release of TypeScript 1.0 at the BUILD developer conference and is now taking pull requests for bug fixes, improving documentation and "general cleanup".
Getting to Version 1.0 is a big milestone for any new language and TypeScript, which we first heard about when Microsoft announced it in October 2012 has achieved it more quickly than most.
If you are not clear where TypeScript fits into the ever expanding landscape of programming languages, here is how Jonathan Turner, program manager for the TypeScript team, describes its role in his announcement of Version 1.0:
As reported six weeks ago, TypeScipt is fully integrated into Visual Studio. It is available as part of Visual Studio 2013 and Visual Studio Web Express 2013 Spring Update and as a power tool for Visual Studio 2012 providing an development environment with Intellisense, project support, and powerful code navigation features. Community-contributed plugins for editors such as Eclipse also offer capabilities such as statement completion, early errors, linting, and more.
Although initiated by Microsoft’s Anders Hejlsberg and largely developed within Microsoft, TypeScript is an open source project under an Apache 2.0 licence and Version 1/0 is available as an npm package, and as source.
Now, however, it intends to be "more open" and Turner's announcement included the news that the team will begin taking pull request for the TypeScript compiler and language service. To contribute a bug fix you first need to complete a CLA (Contributor Licence Agreement and the information the pull request needs to include is outlined on the Guidelines for Contributors on the TypeScript wiki.
