Frameworks
  Angular - made by Google
  Backbone - backend framework
  Knockout
  Ember
  React
  VueJS - newer, and fast

Writing plain vanilla JS can do most of the things frameworks do, but frameworks makes it faster to write, though less flexible

Two way binding
  Where it is stored and where it is displayed are connected, if you change one it changes the other

In Vue writing a for loop
  <li v-for="review in reviews">{{ review }}</li>
  formatted as blockvariable in array

Arrays are ordered lists, hashes are unordered lists
Array is a list of elements denoted by [] with elements separated by commas
Hashes are lists of key value pairs, with both key and value separated by commas


JS Functions written in twi different ways

standard/traditional syntax
  function exampleFunction() {
   //logic
  }

first citizen function
  {exampleFunction: function(arg) { logic }, time: "7:30pm"};

  or

  var exampleFunction = function() {
  };


Objects must be able to store behavior (what it does) and attributes (what it is)

Strings can act as arrays themselves so you can run methods on strings as if they were arrays
