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.

# The OAuth access token provided by the Google API expires in 60 minutes. After expiration,
# you must exchange a refresh token for a new access token. Unfortunately, the the Google API 
# ruby gem does not include a method for refreshing access tokens. 

# You can read up on how to refresh an access token here: 
# https://developers.google.com/accounts/docs/OAuth2WebServer#refresh

# This Token model implements that process. It's based off of a Token model that can be created 
# by running: 
# rails g model Token token:text refresh_token:string expires_at:datetime
