Admittedly I haven't used it much, but it strikes me as a superset of JavaScript for C# developers and a slight rehash of JScript. This should be no surprise, as it is a Microsoft initiative and doubtless enables .net developers to achieve a higher level of full stack productivity.

While its compatibility with Visual Studio's debugger is excellent and it can in theory output highly performant JS, I have to say that, having myself approached C# only after JS, and having a better knowledge of JS than the former, I don't really see the point in writing typesafe code that's eventually transpiled for a non-typesafe interpreter.

While I'd agree its a natural stepping stone for c# devs that's not it's origins. Typescript is a superset of JavaScript and the roots of its optional static typing where laid down many years ago with ActionScrript and the abandoned ES4 spec.

Thanks. You do make some valid points and would like to pick your brain a bit further :-)
a) What about organisation? Did you feel like it easier to work on a team and share code? 
b) Did you had any problems with the compiled code?

Hello! So sorry I didn't write back. And thank you lordhanson - I didn't know that, but it makes perfect sense. To answer your question, coffee:

a) I did, yes, as statically typed code is much easier to reason about. TypeScript is naturally a little more verbose than plain JavaScript, but what it lacks in brevity it more than makes up for with clarity.

b) Nope, no problems; I use Browserify a lot so tsify was a natural choice of tooling for me. But there are many options available to support whatever you're using to compile modules.

I may well end up using TS exclusively going forward, especially due to the quality of code produced using TS + ES6. It's a Microsoft-backed project and seems it's around to stay, so my conclusion is that it's well worth taking it up if it piques your curiosity sufficiently after one or two tries.
