EID Runtime Exceptions and Utilities for JavaScript

You'll need node / npm and tsd installed globally. To get up and running just enter:

npm install
tsd install
npm run test

This will:

1. Download the npm packages you need
2. Download the typings from DefinitelyTyped that you need.
3. Compile the code and serve it up at http://localhost:8080

Now you need dev tools. There's a world of choice out there; there's Atom, there's VS Code, there's Sublime. There's even something called Visual Studio. It's all your choice really.
