Lesson: Introducing JavaScript Object Notation JSON

JavaScript Object Notation or JSON uses the format of JavaScript Objects to store data. JSON is flexible because it allows for Data Structures with arbitrary combinations of strings, numbers, booleans, arrays, and objects.

Here is an example of a JSON object:

var ourMusic = [
  {
    "artist": "Daft Punk",
    "title": "Homework",
    "release_year": 1997,
    "formats": [
      "CD",
      "Cassette",
      "LP" ],
    "gold": true
  }
];

This is an array of objects and the object has various pieces of metadata about an album. It also has a nested formats array. Additional album records could be added to the top level array.
