# How to use this script:
# 1. Follow these instructions to configure a single AWS account to do initial login with SSO
#    https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-sso.html
# 2. Export AWS_PROFILE=... and then run "aws sso login" to get an SSO token
# 3. Once signed in with AWS SSO, run this script to automatically list out all the other accounts and roles and add them to your config file

# If you want to filter roles / accounts in the process, or validate config before committing it, you can customise the script to do this.

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.
