I've just recently heard about TypeScript and I took quite an interest in it.
My biggest disappointment was that only Visual Studio 2012 supported. I think TypeScript is currently missing a decent tool that everyone can write script in. So I was thinking to myself a good notepad with IDE like features (like IntelliSense, Building,
Syntax Highlighting) is needed. I'm a .NET WinForms developer and unfortunately that limits me to Windows. I thought what about write the notepad in HTML and TypeScript?
I don't know what the limitations will be of a client application.
