// 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();

// More modern version of what's found here by Khan academy: https://github.com/martinandert/react-interpolate-component/blob/master/index.js

// 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 ",

// 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' };
