Module 0: What you'll need to get started

Notes: Intro (All the cool stuff you can build)

M1 (should m1 be blinking light alone?) Then we reinforce it with each module…

	/**
	* Stringifies a function, and wraps it in an IIFE so it'll auto execute.
	* @remarks The assumption is that you'll be inlining this function into a vanilla \<script\> tag on the page.
	* Therefore you should follow these rules:
	* Standalone code. No imports / or deps on other files / methods.
	* You can use TS, but carefully watch how the output is compiled down to ensure it works for the lowest browser target.
	* Ensure safety. Anything that can fail should likely be wrapped in a try/catch.
	* This will likely be used as blocking js. Keep it short!
	* @param parameter1 - Allows passing a 1/2 string\|number param to the function to be inlined.
	* @param parameter2 - Allows passing a 2/2 string\|number param to the function to be inlined.

	// weirdness with closures
	// Setup: pass an obj to a function, and then another function (in my case apollo server)
	// Test: the thing is executed, then I change the object, then execute again. What is the object value passed in?


	var mockReqObj = { test: 'jamis' };

	// Variation 1)
	// appears to use default value in console log (for both)
	mockReqObj = { test: 'NBODOy' };

	// 1) simple way to result in <div>Hello</div>
	let a = React.createElement("div", null, "Hello");

	// 2) Create a fragment instead of a div so you can pass in JSX as one of the children. Key is optional I think
	// <Fragment key="0">Hello my friend, <a href="http://www.cnn.com">This is good</a> </Fragment>
	let b = React.createElement(
	React.Fragment, {key: 0},
	"hello my friend ",

	var pathArr = pathQuery.split('.');
	var currentVal = base;

	if (!currentVal) {

	// simple example of how to create a function that calls a middleware chain, similar to express middleware

	var req = {type: "req"};
	var res = {type: "res"};

	// 3 middlewares
	var first = function(req, res, next) {
	req.first = true; //easy way to verify that all have been executed
	res.first = true;
	return next();
