First Question

Given the following code list the order of console.logs:

console.log("Hello")

fetch('https://randomuser.me/api/')
  .then( res => res.json() )
  .then( data => {
    console.log("Hi") 
  })

console.log("Sup?")

Second Question

When fetchData is executed what will be console logged?

function fetchData(){
        var data = fetch('https://randomuser.me/api/')
          .then( res => res.json() )
          .then( res => res )
        console.log(data)	
}

What will be console logged when the following code is run? Why?

function fetchData(){
        var data = fetch('https://randomuser.me/api/')
          .then( res => res.json() )
          .then( json => console.log(json) )
}

fetchData()

What will be console logged when the following code is run? Why?

function fetchData(){
        var data = fetch('https://randomuser.me/api/')
          .then( res => res.json() )
          .then( console.log )
}

fetchData()

Third Question

In your own words: what does asynchronous mean?

Fourth Question

Write out the request and response cycle. What is its purpose? How does it work?

Fifth Question

Check out the JSON you get from making a GET request to this url (https://randomuser.me/api/). Open up the Github repositiory for this reading and view the provided src/index.html file in the browser. In src/index.js, make an AJAX request to that url when the button is clicked and append the retrieved information to the DOM. Use the labels to append the right data in the appropriate h4's, h3's and img tags.
