TreeHouse: JSON

JSON explanation

// The weather data is being returned in a format called JSON.
// Let's take a look at the data itself to help explain what JSON is and how it's used.

// First things first.
// JSON spelled J S O N in all caps stands for JavaScript Object Notation.
// The basic idea behind JSON is that we can represent data in this simple to
// read manner, that is easily parsed and used by programming languages.
// JSON is used for mobile data transfer because it is light and small
// JSON is all data, no methods

// Jason is built on and can be represented by two types of structures.
    1. collection of key-value pairs that can be grouped together as an object
    2. ordered list of objects, which we can think of as an array or list.
