CLI Basics

Basic Commands

Let's read about a couple of the most common commands that you're going to use.

ls = "list directory"; lists all files and folders in the present working directory (where you currently are).

pwd = "present working directory"; tells you where you currently are!

cd foldername = "change directory"; switches to the directory named 'foldername'. 'foldername' is always a child of the pwd (present working directory).

Sequelize + Express Starter Guide

Based off of: http://docs.sequelizejs.com/en/1.7.0/articles/express/

Create your project directory

Create and initialize your a directory for your Express application.

$ mkdir sequelize-demo

Gulp + SCSS + LiveReload

This Gist outlines the gulp workflow that will:

watch for any scss changes, then compiles scss source into css
watch for any changes in the public directory, and trigger live-reload
serve static content in public/

This Gist also assumes you already know how to install npm modules, gitignore, create directories and create files via the command line.

###Email Hell

We just found out that there is a bug in production that our e-mail function was iterating errantly and sending duplicate e-mails to many users. We need to fix this quickly but we don't want to send out a mass apology letter to all of our users.

Our sysadmin gave us the SMTP logs and we need to process the logs and identify which users received multiple e-mails so that we can directly send them a follow up e-mail explaining the situation and offer super cool swag to keep them on as customers.

Also, the boss wants this done ASAP, we don't have time to do this manually...HAAALLLLPPP!

###The Fix

###Good Morning Agents

Your challenge this morning is to create a function that implements an algorithm using the concepts we've covered this week.

###Challenge

Write an algorithm that takes in 2 strings as parameters (source, find).
Your function should return true if the string passed in as the find parameter is found in the source parameter if source were circular in nature. Meaning there is no end to the source string.
Important: A match would be true if the word to find is partially at the end of the word and at the beginning in sequence.

Ex.

	// Example component that utilizes FormContext
	import React, { useContext } from "react";
	import { FormContext } from "contexts.js";

	export default function FirstNameInput() {
	const { form, setForm } = useContext(FormContext);

	const handleChange = key => event => {
	setForm({ ...form, [key]: event.target.value });
	};

	import React, { Component } from "react";
	import { withRouter, Redirect } from "react-router-dom";
	import { Authenticator } from "aws-amplify-react";
	import { Auth, Logger, JS } from "aws-amplify";

	import {
	CustomSignIn,
	CustomSignUp,
	CustomConfirmSignIn,
	CustomConfirmSignUp,
