Ajax - Getting JSON from HTTP request

XHR - XMLHttpRequestObject

• Set function for when XHR status changes
• Will need to test if XHR is "DONE" and if we got a successful response (e.g. HTTP 200)
• Will need to parse the text as JSON

Javascript "fetch"

fetch(url).then(response => response.json()).then(data => processData(data));

jQuery makes this easier with the ".getJSON" method!
