Echo JS 0.11.0

I've been using TypeScript now for over 2 years and have to say I love it. Being able to use future JavaScript language features years before they are common in browsers is a massive win. But the optional type annotations are a must for apps of scale. We have a large code base built entirely using TypeScript and there's 7 Ui devs all working on it in parallel. The typing info makes that process far more resilient and allows us to refactor core parts of the application quicker and safer. 

You still need unit tests, but a compiler is a good friend and shouldn't be under valued. 👍
