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

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

Think of them as as lazy evaluation applied to data.

	// String utils
	//
	// resources:
	// -- mout, https://github.com/mout/mout/tree/master/src/string

	/**
	* "Safer" String.toLowerCase()
	*/
	function lowerCase(str) {
	return str.toLowerCase();

	Secure sessions are easy, but not very well documented.
	Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

	The desired configuration for using NginX as an SSL proxy is to offload SSL processing
	and to put a hardened web server in front of your Node.js application, like:

	[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

	Edit for express 4.X and >: Express no longer uses Connect as its middleware framework, it implements its own now.

	var [a, b] = [1, 2];
	console.log(a, b);
	//=> 1 2


	// Use from functions, only select from pattern
	var foo = () => [1, 2, 3];
