Support for TypeScript
As support for ASP.NET and JavaScript has been existing in ReSharper for some time, support for TypeScript is a new feature that comes with ReSharper v8.1.
TypeScript is a typed superset of JavaScript that compiles to plain JavaScript. It allows you to write JavaScript in manner that is similar to C#. As TypeScript is very similar to JavaScript, ReSharper comes with a very similar support for it.
Same as with JavaScript, ReSharper provides you with Smart IntelliSense and templates.
You can navigate through your code by navigating to the File Structure | Go to File Member options. You can find your code dependency and use some simple refactoring methods such as Rename or Introduce Variable.
Remember that ReSharper v8.1 is the first version to provide support for TypeScript, so you can be sure that future versions will come with more.
