Test of a reverse HTTP request. Server will send data first, then wait for input from the client based on the data. Rude ugly code but it actually works.
var http = require('http');
var options = {
hostname: '192.168.56.101',
port: 1337,
path: '/',
method: 'POST'
};
var i = 0;

Example use of databases with Promises
var Q = require('q');
var DB = require('db');
// These DB initializations would probably not be synchronous in a real
// app. You could use Q.spread(), etc. See sample #2.
var db1 = DB.openSync("db1");
var db2 = DB.openSync("db2");
var db3 = DB.openSync("db3");

Funny thing with json_decode...

$ php
<?php echo var_export(json_decode("true ", true), true) ?>
NULL

(Press ctrl-d after you write "?>".)

The same using node.js:
