Microsoft started October with a bang, unveiling Anders Hejlsberg’s newest creation: TypeScript, a superset of Javascript aimed at making the language’s big jobs easier. Key features of TypeScript include:
- module support
- class declarations
- static typing
- a Visual Studio 2012 plugin

During the past five years, JavaScript speed has doubled every nine months (as measured by the WebKit SunSpider JavaScript benchmark.) With HTML5, the standard web platform has become significantly more compelling for delivering rich user experiences. At the same time, the reach of JavaScript has continued to expand, going beyond the browser to include native device apps (e.g. Windows Store apps for Windows 8), applications in the cloud (e.g. node.js running on Windows Azure), and more. With these developments, we’re starting to see applications of unprecedented size written with JavaScript, despite the fact that creating large-scale JavaScript applications is hard. TypeScript makes it easier.
