##what are generators##

They're pausable functions, pausable iterable functions, to be more precise
They're defined with the *
every time you yield a value, the function pauses until .next(modifiedYieldValue) is called

var myGen = function*() {
  var one = yield 1;
  var two = yield 2;
  var three = yield 3;
 console.log(one, two, three);

Go Concurrency Patterns

Generator: function that returns a channel

package main

import (
	"fmt"
	"math/rand"

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

Remove MySQL completely

Open the Terminal
Use mysqldump to backup your databases
Check for MySQL processes with: ps -ax | grep mysql
Stop and kill any MySQL processes
Analyze MySQL on HomeBrew:
```
brew remove mysql
```

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

	# lib/tasks/db.rake
	namespace :db do

	desc "Dumps the database to db/APP_NAME.dump"
	task :dump => :environment do
	cmd = nil
	with_config do \|app, host, db, user\|
	cmd = "pg_dump --host #{host} --username #{user} --verbose --clean --no-owner --no-acl --format=c #{db} > #{Rails.root}/db/#{app}.dump"
	end
	puts cmd

	#add 'node_modules' to .gitignore file

	git rm -r --cached node_modules
	git commit -m 'Remove the now ignored directory node_modules'
	git push origin <branch-name>
