	# This file is auto-generated from the current state of the database. Instead
	# of editing this file, please use the migrations feature of Active Record to
	# incrementally modify your database, and then regenerate this schema definition.
	#
	# Note that this schema.rb definition is the authoritative source for your
	# database schema. If you need to create the application database on another
	# system, you should be using db:schema:load, not running all the migrations
	# from scratch. The latter is a flawed and unsustainable approach (the more migrations
	# you'll amass, the slower it'll run and the greater likelihood for issues).

Examples of sequential, concurrent and parallel requests in node.js

Concurrency in JavaScript

Javascript is a programming language with a peculiar twist. Its event driven model means that nothing blocks and everything runs concurrently. This is not to be confused with the same type of concurrency as running in parallel on multiple cores. Javascript is single threaded so each program runs on a single core yet every line of code executes without waiting for anything to return. This sounds weird but it's true. If you want to have any type of sequential ordering you can use events, callbacks, or as of late promises.
