AJAX - a way of getting info form api to javascript
     - can refer to any web request from inside the code (from an api)

JQuery Library - used in 90% of websites
               - standardized code between browsers


In JS hashes are treated as objects so you can use the [] notation or the .exampleattribue notation

JS is asynchronus language so if a funcition is delayed it is put in a queue and other functions
will run even if written lower down in the code

Callback - as soon as a JS funciton runs the next will run
  ex) setTimeout(function() {
        console.log("First Task Done!");
          setTimeout(function() {
            console.log("Second Task Done!");
            setTimeout(function() {
              console.log("Third Task Done!");
                setTimeout(function() {
              console.log("Fourth Task Done!");
            }, 2000);
          }, 2000);
        }, 2000);
      }, 2000);
