A quick overview of the node.js streams interface with basic examples.

This is based on @brycebaril's presentation, Node.js Streams2 Demystified

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

	What happens?
	- `new Type().what` is looked up with a call to `get` on the proxy
	- a function is returned that will look up `METHOD_NAME` when called
	- `METHOD_NAME` is called because of the `()` behind `new Type().what`
	- if `METHOD_NAME` exists on you object, your own function is called
	- if not, because of prototypal inheritance, `get` is called again
	- `name` is now `METHOD_NAME` and we can throw as we know `METHOD_NAME` is not implemented on the type

	// from google javascript style guide:
	// One thing to keep in mind, however, is that a closure keeps a pointer to its enclosing scope. As a
	// result, attaching a closure to a DOM element can create a circular reference and thus, a memory leak.
	// For example, in the following code:

	// Leaky example
	function foo (element, a, b) {
	element.onclick = function() {
	// uses a and b
	// this func keeps a pointer to foo, its enclosing scope
