Useful TypeScript Links

TypeScript is a strongly typed open source language which compiles into JavaScript. TypeScript was originally developed by Microsoft.  The language supports interfaces, classes (including inheritance), generics and modules.

Using TypeScript enables the developer to validate the code contracts at design/compile time instead of waiting until the code is executed in the browser.  This reduces your development and testing costs and results in a more reliable site.

This YouTube video provides a good introduction to the language including how to integrate jQuery with TypeScript: Getting Started with TypeScript

There is a browser based playground at: http://www.typescriptlang.org/Playground which you can use to try out the language.

Many TypeScript type definitions (which are very useful when incorporating other JavaScript frameworks such as jQuery) are available on github: https://github.com/DefinitelyTyped/DefinitelyTyped
