jsig - precise & concise JavaScript signature notation

Sure, JavaScript is a dynamically typed languages, but I've found having an explicit notation to be the fastest way to communicate to another developer how to use a module I've written.

I wrote up jsig - JavaScript signature notation - to formalize the notation we've been using in our codebase at work and in the documentation for my npm modules.

Here's what it looks like:

 // ({stderr: ReadStream, stdout: ReadStream }) => void
function log(stdio) {
  file = require('fs').createWriteStream('io.log')

jsig helps write clear, accurate function comments and documentation with fewer words and less ambiguity.
