title: TypeScript Web-Based IDE
body: <p>Given the fact that TypeScript is Open Source, is <a href="http://www.typescriptlang.org/Playground/">this Web-Based IDE</a> also available as a tool that can be downloaded anywhere?</p>
  
  <p>I'm developing a web application in which the client can write a user-defined expression (with user-defined variables and predefined methods) which is evaluated, compiled and used at runtime on the server using C# .Net. Using TypeScript and its wonderful web-based editor's features like syntax or error highlighting, code completion, method signature suggestion, etc,  saves me lots of trouble in the user interface.</p>
  
  <p>So is this editor also part of TypeScript? If not, is there any other open source solutions with similar capabilities?</p>
